Feeding difficulties in premature babies
Feeding Difficulties | Patient Education
Patient Education A-Z
When babies are born prematurely, their digestive systems may not be fully developed. As a result, many of these small infants experience feeding difficulties such as:
- Problems establishing nipple feedings, at breast or with the bottle. This may occur because the infant can't suck and swallow properly.
- Gastric residuals, which occurs when babies don't completely empty their stomachs from a previous feeding.
- Gastroesophageal reflux, which occurs when a small amount of stomach contents, including stomach acid, refluxes or regurgitates into the esophagus. This can be painful to the infant and, when severe, may cause signs of distress such as apnea, a condition in which a baby temporarily stops breathing.
- Abdominal distension, which is an abnormal enlargement or swelling of the stomach. This distension may be a sign of more severe gastrointestinal problems.
Feeding is given special attention in the Intensive Care Nursery at UCSF Benioff Children's Hospital. Babies born before weeks 32 to 34 of pregnancy usually can't nurse or drink normally from a bottle. Instead, these babies receive nutrients by gavage feedings, in which a tube is placed through their mouth or nose into their stomach.
Although many premature babies can't breastfeed because they can't coordinate sucking, swallowing and breathing, mothers can still pump breast milk; the staff of the Intensive Care Nursery will store it and feed it to your baby by gavage feedings.
In almost all infants, feeding difficulties are temporary and resolve as the baby matures and gets closer to the full-term due date. However, some infants may suffer from more severe feeding problems that can lead to other conditions, such as necrotizing enterocolitis, or NEC. As a serious problem of the intestines, NEC affects a very small percentage of extremely premature babies and may require temporary stopping intestinal feedings, treatment with antibiotics and, in severe cases, surgery.

Share:
When babies are born prematurely (before 37 weeks of pregnancy), they may have special feeding and nutritional needs. Preemies often need extra support to grow and continue developing, and parents may have questions about breastfeeding, bottles or feeding schedules.
Kikelomo Babata, M.D., a neonatologist at Children's Health℠ and Assistant Professor at UT Southwestern, answers these questions and shares advice for feeding your premature baby.
What are common feeding problems in premature infants?
Premature babies may face different feeding problems depending on their age and development. "Post-conceptual age is more important than chronological age for a baby's development," explains Dr. Babata. "A 4-week-old infant born at 32 weeks may not be as developmentally ready to feed as a 2-week-old infant born at 35 weeks.
And every baby is different."
Some premature babies have difficulty breastfeeding or bottle-feeding for the first few weeks of their lives. This is because infants, both full-term and premature, continue developing their ability to suck, swallow and breathe after birth. This is a skill they need to feed, so they can coordinate how to suck, swallow then breathe through their nose. Additionally, premature babies may be sleepy and get tired during their feeds.
Premature infants might also have underdeveloped lungs. They might need to be on oxygen, which can make it difficult for them to eat.
Other common feeding problems in premature babies can include:
- Apnea (episodes where they stop breathing)
- Episodes of bradycardia (slow heartbeat that can cause oxygen levels to drop)
- Immature feeding pattern (sucking, swallowing and breathing incorrectly or out of order)
- Oral aversion (not taking a bottle or breast)
- Risk of aspiration (breathing in milk or formula)
If your baby experiences these feeding problems, they may need to be fed through a feeding tube.
This tube is placed through the nose and down into the esophagus. If your baby has a feeding tube, they'll stay in the hospital until it is removed.
Once your baby goes home, your pediatrician can offer tips on feeding your baby and the importance of good nutrition. If needed, they can refer you to speech therapist for more support.
Can I breastfeed my premature baby?
Yes, you can breastfeed a premature baby. Your breastfeeding experience may depend on your baby's development and nutritional needs.
Breastmilk offers many benefits for premature babies, such as:
- Boosting digestion
- Helping baby’s immune system fight infection
- Promoting eye and brain development
- Providing bonding opportunities
"Breastmilk is linked to a lower risk of necrotizing enterocolitis, an illness that can be devastating for preterm infants," says Dr. Babata. Necrotizing enterocolitis is inflammation that can seriously damage or destroy intestinal tissue in babies.
It can increase their risk of death or neurodevelopmental problems.
Breastfed infants also have a lower risk of ear infections, respiratory infections like respiratory syncytial virus (RSV) and bronchiolitis, rashes and gastroenteritis. Breastfeeding can have long-lasting benefits as well – lowering your child's risk for chronic illnesses in the future.
Advice for breastfeeding a premature baby
It's important to know that breastfeeding a premature infant might look different than breastfeeding a full-term infant. Breastfeeding may take more coordination for a preemie than bottle feeding, and depending on how premature your baby is, they may have difficulty latching. You may need to use bottles for a few weeks if your baby is having difficulty nursing. You can still choose to pump and provide breastmilk in a bottle. See tips for increasing your milk supply while pumping and how to safely store your breast milk.
If your premature baby can breastfeed, they still might need bottles of supplemental formula.
Often, premature babies cannot exclusively breastfeed because they have higher caloric needs to support growth. Special high-calorie formula or human milk fortifiers can help your child grow while still getting the benefits of breastmilk.
If your premature baby is on a feeding tube, talk to your care team to learn what you can do and whether you should pump your breastmilk.
What type of bottle and formula is best for my premature infant?
Whether you give breastmilk or formula in a bottle, you should use a slow flow bottle nipple designed for premature infants. These bottle nipples help prevent your baby from getting more liquid than they can handle at once.
Most premature babies will use a special formula designed for preterm babies. Your pediatrician or neonatologist can recommend the right formula for your baby's needs. Depending on your baby's diet, they can also advise if any other nutritional supplements are needed, such as vitamin D or iron.
How much should I feed my premature baby and how often?
How much your baby needs to eat will change as they grow. Premature babies need 150 to 160 milliliters per kilogram of body weight each day. Your lactation consultant or pediatrician can help you determine how much this is for your baby.
No matter how much they eat per feeding, preemies need to eat at least every 3 to 4 hours.
When can my premature baby eat solids?
A premature baby can start eating solid foods when their adjusted or conceptual age is 4 to 6 months. A conceptual or adjusted age means that instead of counting your baby’s age from their date of birth, it's calculated from their due date. For instance, if your baby is born 10 weeks before their due date, their age at 10 weeks past their due date is 10 weeks (even though they were born 20 weeks ago).
Around the adjusted age of 4 to 6 months, premature babies should be able to support their head and have lost their tongue-thrust reflex.
This reflex causes them to spit out anything put in their mouth that's not milk or formula. This is a good time to introduce solids.
Taking care of a baby is a challenging job. While these special feeding needs can add extra stress to those early days of your child's life, parents should remember that patience is key.
"Most babies will eventually learn to feed orally," says Dr. Babata. "Just take it one step at a time and be sure to notice and enjoy progress as it occurs."

Feeding premature babies | Breastfeeding premature babies
Premature babies have a special need for breast milk, but it can be difficult to breastfeed them directly. Our expert advice will help you provide your premature baby with healthy breast milk.

Professor Katsumi Mizuno, Department of Pediatrics, Showa University Koto Toyosu Hospital:
Katsumi is a Certified Breastfeeding Consultant, Professor of Pediatrics at Showa Medical University, and one of Japan's leading pediatric neonatologists. His research focuses on neonatal suckling skills, breast milk banking, and the use of breast milk for feeding premature babies in neonatal intensive care units.
Babies born before the 37th week of pregnancy are considered premature. 1 The causes of preterm birth are not always obvious, but certain factors increase the likelihood of such an event. These include: twin or multiple pregnancy, certain diseases of the mother or fetus, as well as a history of premature birth.
Because premature babies spend less time in the womb, they are not mature enough and may be more susceptible to infection and disease. They often require hospitalization in the neonatal intensive care unit.
Why is breast milk so important for premature babies?
Breast milk is essential for optimal growth and development of term babies, but it is even more important for premature babies.
During pregnancy, the fetus receives important substances from the mother through the placenta, such as DHA (a fatty acid essential for brain and eye development) and immunoglobulin G (an antibody). 2.3 A premature infant did not receive all of these substances.
However, the milk produced by a premature mother contains more fat and secretory immunoglobulin than mothers of full-term babies. 4
In addition, premature babies have an underdeveloped gastrointestinal tract, which can make digestion and absorption of nutrients difficult, so they need food that their sensitive stomach and intestines can easily digest. Breast milk contains enzymes that make it easier for the baby to digest, 5 as well as epidermal growth factor, which accelerates the development of the gastrointestinal tract 6 . Premature infants who are predominantly breastfed have much lower intestinal permeability than formula-fed infants, meaning fewer potentially harmful particles from the stomach and intestines enter their bloodstream. 7
Breast milk is so important for premature babies that if the baby's mother does not produce enough breast milk at first for any reason, it is recommended that the deficiency be replenished with donor milk rather than formula.
Does breast milk improve the condition of premature babies?
Breast milk contains protective substances that can prevent serious diseases that preterm infants are susceptible to, 8 such as severe infections, 9 retinopathy of prematurity (which can cause vision loss) 10 and bronchopulmonary dysplasia (chronic lung disease). 11
The more milk your baby gets, the lower the risk of developing diseases. 12 Every additional 10 ml of milk per kilogram of body weight per day reduces the risk of sepsis by 19%. 9 The risk of developing necrotizing enterocolitis (a potentially fatal bowel disease) in premature infants who are breastfed is ten times lower than those who are formula fed. 13 That's why every drop counts!
Most importantly, premature infants who are breastfed are typically discharged an average of two weeks earlier than formula-fed infants. 14 They also have a 6% lower risk of readmission in the first year of life.
15
Breast milk has been proven to have a beneficial effect on mental and physical development in the long term. Studies show that low-birth-weight babies who are breastfed in the neonatal intensive care unit have an average IQ of up to five points higher than those who are not breastfed. 15 In addition, their cardiovascular system works better during their lifetime. 17
Will milk be produced if the baby is born prematurely?
Yes, the mother's body is ready to produce milk by the middle of pregnancy. After the baby is born and the placenta is born, the level of progesterone, the pregnancy hormone, drops, and the production of colostrum, the first milk, starts in the breast. This usually happens after the newborn is put to the breast and begins to suckle rhythmically, but if the baby was born prematurely, he most likely will not be able to latch on at first.
To replicate the sensations that trigger milk production, you can manually stimulate the breasts and nipples, or use a breast pump to express nutrient-rich colostrum for your baby.
18 Read below for more information on what to do if your premature baby is not yet able to breastfeed.
Breast milk usually comes in two to four days after birth, but if it was premature, the milk supply may be delayed. However, a recent study shows that moms who started pumping within one hour of giving birth had milk coming in as expected. 19 This is why it is important to start expressing breast milk as early as possible.
How to prepare if the baby is expected prematurely?
Visit the neonatal intensive care unit to see how it works and how premature babies are cared for. In addition, it will be useful to learn how breast milk is produced and secreted and why it is not only a healthy food, but also an important medicine for premature babies. Read more about this in our free e-book Surprising Breast Milk Facts .
What if a premature baby cannot breastfeed?
Many babies born before 34 weeks have difficulty coordinating sucking, swallowing and breathing.
Until the baby masters these skills, nurses will feed him through a tube that is inserted into the nose or mouth and provides food directly into the stomach. In this way, the baby can be fed continuously until he is ready to breastfeed.
If your baby is too weak to latch on and suckle milk, you can use a breast pump* available at the hospital or maternity hospital to “do the job for the baby”. Breast stimulation with research-based technology, 20 mimics the rhythm of the baby's suckling, plays an important role in starting and maintaining milk production in the first hours after birth 21 .
Milk should be expressed at the same frequency as term infants are usually fed every two to three hours, i.e. 8 to 12 times a day.
You can try putting a small amount of expressed breast milk into the baby's mouth with a syringe, or putting milk-soaked cotton swabs in the baby's mouth. 22 This is how your baby learns the taste of your milk, which will facilitate the transition to breastfeeding in the future.
In addition, the protective substances that make up breast milk will help strengthen the local immunity of the baby's oral cavity. You can be involved in the care of your premature baby in a variety of ways - check with your healthcare provider for details.
Very low birth weight babies - less than 1.5 kg - usually need extra protein, calcium and phosphorus, so they are given fortified breast milk. In some countries, such additives are made on human milk, and, for example, in Japan, on cow's milk.
Recommendations for pumping milk
If the baby will be in the neonatal intensive care unit for a long time, neonatologists recommend using a double breast pump for pumping. I always recommend Medela Symphony*. Double pumping not only speeds up the process, but also produces an average of 18% more milk than pumping from each breast in turn. 23
In addition, I advise you to create the most comfortable conditions for pumping. It is generally agreed that it is best to express milk during or after prolonged skin-to-skin contact with the baby (more on this "kangaroo method" below).
Another good option is to sit next to the crib and watch your baby while he pumps. Oxytocin (the hormone that stimulates milk flow) is released when you look at your baby, touch him, smell him and think about him, 24 Therefore, comfortable and calm conditions must be created for this in the neonatal intensive care unit.
What is kangaroo care for premature babies?
The so-called kangaroo method involves prolonged skin-to-skin contact between parents and infant. This is extremely beneficial for you and your baby, as well as for milk production. Skin-to-skin contact normalizes the baby's breathing and heartbeat, keeps him warm and allows him to be as close to the parent as possible. Kangaroo care is believed to have a beneficial effect on the health of premature babies, 25 and it helps mothers express more milk 26 and breastfeed longer. 27 Skin-to-skin contact 30-60 minutes before feeding gives baby time to wake up and be hungry so he can eat without being forced.
What if the neonatal intensive care unit offers formula feeding?
Feel free to state that you want to breastfeed your baby instead of formula. If you don't have enough breast milk to feed your baby, ask the ward for help to increase your milk supply.
It is natural for mothers whose babies are in the neonatal intensive care unit to experience anxiety and stress. Sometimes these experiences interfere with milk production, so it's important to ask for any help you may need. Remember that you have the right to seek support. Your healthcare provider may be able to recommend a suitable lactation specialist, such as a lactation consultant, for you.
How to switch from pumping to breastfeeding?
At whatever gestational age a baby is born, if the baby is stable enough for skin-to-skin contact, it can seek the breast for sedative suckling. This is the perfect way for your baby to learn sucking skills before they learn to coordinate sucking, swallowing and breathing.
Babies love the smell of breastmilk, so you can put some milk on the nipple before putting your baby to the breast to make him want to suckle. He might even be able to suck some milk. Don't worry if your baby seems to suck very little - he learns every time. He can start with one or two sips and gradually move on to full breastfeeding. Until then, the baby can be fed through a tube, pressed to the breast, so that the taste of milk and touching the breast is associated with a feeling of satiety.
You can put your baby to the breast for sedative suckling as soon as you are ready for kangaroo care, unless your baby is suffering from bradycardia (slow heartbeat) or low oxygen levels in the blood. You can switch to breastfeeding as soon as the baby is ready for it. Gradually, he will gain enough strength to suckle longer and suck out more milk.

Peculiarities of feeding premature babies
Successful nursing of premature newborns, in addition to therapeutic measures, largely depends on the creation of optimal external conditions and adequate nutrition. According to modern theory of nutrition programming the quantity and quality of nutrients supplied during the prenatal period and the first months of a child's life determines the nature of metabolism and, as a result, affects a person's health throughout later life.
Proper and nutritious nutrition in the early stages of life affects the overall development of the child, and also contributes in direct proportion to the reduction of the development of chronic diseases in adulthood (such as diabetes and arterial hypertension).
The purpose of enteral nutrition is to provide the body with the nutrients it needs to grow and develop.
Providing a premature newborn with an optimal amount of nutrients is quite difficult, given the morphofunctional immaturity of the digestive system and the lability of metabolic processes. The relatively high need of premature infants for nutrients is in conflict with the limited ability to assimilate them.
Feeding methods for premature babies are determined by the severity of their condition and depend on the body weight and gestational age of the baby at birth.
Successful feeding of a newborn is possible when sucking, swallowing and breathing become well coordinated.
The swallowing reflex is well developed already by 28-30 weeks of gestational age, but it is very quickly depleted. Fully matures by 34 weeks of gestation. When does sucking and swallowing coordinate? Already at 28 weeks of gestational age, all the components of sucking and swallowing take place, but the child is not yet able to coordinate them.
Partially, this occurs by 32-34 weeks of gestation. Coordination of sucking and swallowing fully matures around 36-38 weeks of gestational age. From 37 to 38 weeks of gestational age, newborns are able to coordinate sucking, swallowing, and breathing without difficulty.
When feeding premature babies, you should pay attention to four points: when, with what, in what volume, by what method to feed.
The first feeding should be started as soon as it becomes clinically possible. Earlier introduction of breast milk helps to reduce the frequency of infections, maturation of the gastrointestinal tract, immune functions, and improved calcium metabolism.
Newborns weighing more than 2000 g and gestational age more than 33 weeks, who do not have other diseases, can be attached to the mother's breast as early as the first day of life. In this case, you should carefully monitor the appearance of signs of fatigue (cyanosis of the nasolabial triangle, shortness of breath, etc.
). Their appearance is an indication for the transition to feeding expressed breast milk from a bottle. Efforts should be aimed at preserving breast milk as much as possible, taking into account the special biological value of mother's native milk for an immature child and the important role of mother-child contact during feeding. For premature babies, free feeding is unacceptable due to their inability to regulate the amount of sucked milk and the high incidence of perinatal pathology.
Babies born before 33 weeks' gestation are usually tube-fed to avoid the risk of aspiration resulting from a lack of coordination between sucking and swallowing. With a non-severe condition of the child and a body weight approaching 2000 g, a trial feeding from a bottle can be carried out, with unsatisfactory sucking activity, tube feeding is prescribed in full or in part. In order to maintain and maintain lactation in the mother, regular expression of breast milk is necessary.
Enteral feeding of very preterm infants (weighing less than 1500 g and less than 30 weeks' gestation) is carried out through a tube.
The caloric method is used to calculate the required amount of feeding for premature babies. The calorie content of the diet of a prematurely born child increases gradually and daily.
Caution and Graduality Feeding Guidelines for Premature Babies Less Than 33 Weeks Gestational Age Less Than 2000g
For a premature baby, the best bioavailability is the milk of a woman who has given birth prematurely, then formulas for premature babies, and then the milk of a woman who has given birth at term.
Women's milk after preterm birth has a special composition, it contains more protein, less lactose with the same total level of carbohydrates. In addition, it has a higher content of a number of protective factors, in particular lysozyme and secretory IgA. Despite the special composition, the milk of women who gave birth prematurely can satisfy the nutritional needs of only premature babies with a relatively large body weight - more than 1800-2000 g.
Premature babies with a lower body weight are deficient in a number of nutrients. For them, breast milk must be further enriched with protein, calcium, phosphorus, iron, and vitamins. This can be achieved by replacing part of the required amount of breast milk with a specialized formula for premature babies or by adding breast milk enhancers. When enrichers (enhancers) are used, the main advantages of breastfeeding are preserved and at the same time the high nutritional requirements of the premature baby are ensured. With artificial feeding, specialized mixtures intended for feeding premature babies should be used. Cancellation of specialized mixtures for premature babies and their transfer to standard milk formulas is carried out gradually. The duration of use depends on the gestational age of the child. Premature babies with a gestational age of more than 31-33 weeks should receive specialized formulas until they reach a body weight of 2500-3000 g, after which they are completely transferred to standard adapted milk formulas.
