Reasons your baby sweats while breastfeeding

It is common for babies to sweat while breastfeeding. But it is important to mention it to your pediatrician when you take her for a health check-up. The following are the reasons for your baby to sweat.

Mummy’s skin

While breastfeeding, you and your baby are in close contact, often skin-to-skin and it can make your baby feel warm. It increases your baby’s body heat. To help your baby regulate her temperature, the body stimulates the natural process of cooling by starting to sweat. It is a classic biology stunt. 

Her room is too hot

A warm environment obviously causes your baby to sweat. If you live in a hot and humid place, your baby is more likely to sweat while breastfeeding. That is why; make sure her room is of ambient temperature. She will get fussy while breastfeeding if it is too cold or too hot. It is always a good idea to keep the rooms well-ventilated. It will keep your baby comfortable and will also prevent any stuffiness in the room.

Too many clothes

You should never over-dress your baby. The old norm of layering her up with many clothes is not always applicable. Put on clothes as necessary. Too many layers of clothes in a hot surrounding will cause sweating. Avoid making her wear a cap while she is feeding, as keeping her head bare will help her body to remain cool. If it is cold and you are feeding her during winter months, you can dress up your little one in woolen clothes. 

Use cotton clothes

Cotton clothes are breathable and soft. It will make sure that your baby is comfortable. If you use polyester clothes, there will not be any air circulation. This is another reason why your baby will sweat. During breastfeeding, your baby is close to your skin making it warmer for her. Polyester clothes will only increase her sweating.

Sucking is your baby’s form of exercise

When we exercise and move our muscles, it is common for us to sweat. In the same way, sucking is an exercise to your baby’s jaws. This is a form of exercise for her which makes her sweat. You can let your baby take breaks before you complete breastfeeding.

Why does your baby sweat while breastfeeding: Does it indicate a health issue?

While sweating when breastfeeding is normal, there might be some health issues associated with it. The most common health issues are pulmonary atresia and hyperthyroidism.  

Pulmonary atresia is a condition related to the pulmonary valve of the baby’s body. The pulmonary valve is an opening on the right side of the heart that helps regulate blood flow to the lungs. In the case of pulmonary atresia, the pulmonary valve does not form properly. As a result, the blood from the baby’s right ventricle cannot reach the lungs. It leads to a deficiency of oxygen in the body.

Excessive sweating may also indicate a condition related to the thyroid gland. This condition is called hyperthyroidism. Some babies can suffer from cyanosis or develop a bluish tint to their skin.

If your baby has a health issue that causes excessive sweating while breastfeeding, there will be more symptoms that you need to spot. Here are a few more symptoms you can watch out for:

• Your baby may have difficulty in breathing. She may breathe rapidly or slowly or even gasp.

• Additionally, your baby may always seem tired and lethargic or may fall asleep while feeding all the time.

• In some cases, your baby may not want to feed at all.

Why does your baby sweat while breastfeeding: More tips to reduce baby sweating

Before you get panicked and fill your mind with all sorts of negative thoughts, there are a few tips to decrease your baby’s sweating. Try out these tips before you rush to a doctor.

• While you are breastfeeding, you and your baby will be in a tight embrace. Therefore, it is important that you take care of your clothing as well, as what you wear will also affect your baby. Make sure you dress in light cotton clothes in summer that will help keep both you and your baby cool. Make sure the material is soft on your baby’s skin. If you are feeding during winter months, check that your woollen garment does not touch your baby’s body directly, as it can cause skin irritation.

• Do not cover your baby’s head or face using a cloak while you are nursing her at home. Use a cotton nursing cloak while breastfeeding her in public.

• If your baby does seem uncomfortable, lightly blow air over her head to reduce any sweating.

• Try switching your baby’s position while breastfeeding her. Often, while you are nursing your little one, her head lies cradled in the same position for long. It causes one part of her face and head to heat up, leading to profuse sweating in that area. Make sure you change your baby’s position for some time while switching breasts.

If your baby is still sweating after taking all these necessary measures, you should consult the doctor immediately. Excessive sweating can be a symptom for some major health issue. Now that you know almost all possible reasons for why your baby is sweating while breastfeeding, there is nothing to panic about.

Breastfeeding is like a workout for babies, and just like adults sweat when they exercise, babies sweat while breastfeeding. Sweating or perspiration is the body’s way of keeping itself cool by sending excess heat out of the body. Sweating may happen anywhere on the body, but it is most common on the head, scalp, under the arms, on palms, and the soles of feet (1). Read this post as we explain the causes, management, and signs you need to see a doctor if you notice your baby sweating more than usual when they breastfeed.

Do Babies Sweat When Feeding?

Some babies do sweat while breastfeeding. If the baby’s body temperature rises due to some reason, then the sweat glands release sweat. Certain health conditions might also cause sweating while breastfeeding.

Not all babies sweat while breastfeeding. Read on to know more about the likely causes.

Why Do Babies Sweat While Breastfeeding?

If your baby is sweating during feeding, then it does not mean that there is always a pathological reason for that. A baby might sweat for the following general physiological reasons:

1. Skin-to-skin contact

Image: iStock

While feeding, the baby comes in skin-to-skin contact with the mother. The heat from the mother’s body gets transmitted to the baby’s skin, thus increasing the likelihood of sweating.

2. Room temperature

High room temperature can make a baby uncomfortable and overheated. It can also lead to sweating.

3. Excess covering

Parents may cover the baby in blankets to keep them warm. At times, the mother might cover herself and the baby while breastfeeding in public. Placing a cover over the baby’s stroller or car seat makes it warmer for the baby, even if the cover is thin and breathable. This can overheat the baby and may cause sweating.

4. Warm clothes

Covering the baby in warm clothes can increase body temperature and cause sweating. Making the baby wear a cap during the feeding session might cause sweating on the head.

5. Remaining in the same position

If the baby is held in the same position for a long time, then it may cause overheating and sweating on the part of the baby’s body that is in contact with your skin.

Why Does The Baby’s Head Sweat While Breastfeeding?

In babies, sweat glands are concentrated on the forehead and scalp, thus leading them to sweat more in these regions. The sweat glands gradually develop on the chest, limbs, followed by other parts of the body (2).

When To Consult A Doctor?

See the doctor in the following scenarios.

  • The baby gets tired too soon and does not eat enough or the baby falls asleep right after starting the feed. Consult a lactation consultant IBCLC to assess a feeding and discuss ways to stimulate the baby to actively suckle at the breast.
  • They do not gain enough weight. Reach out to a lactation consultant to assess how breastfeeding is going and identify the cause for slow and/or no weight gain.

  • The baby experiences shortness of breath or labored breathing, or gasps for air while breathing.
  • There is a blue tint on the baby’s skin, probably indicating that they have less oxygen in the circulating blood.

How To Reduce Sweating While Breastfeeding?

The following tips might help reduce sweating in a baby during breastfeeding.

  • Dress the baby in loose and comfortable clothes. The baby’s clothes should be compatible and suitable for the weather or ambient temperature.
  • Choose breathable cotton fabric clothes for your baby. Do not dress them in fabrics like polyester.
  • Avoid wearing woolen or polyester clothes yourself while feeding the baby.
  • Do not put layers of blankets over the baby while breastfeeding. Instead, use a soft and breathable nursing cover.

  • Do not cover the baby’s head while you are breastfeeding them. Putting caps and mittens on the baby might cause excessive sweating.
  • Feed the baby in a well-ventilated room. Keep the temperature of the room comfortable (3).

If none of the tips help in the reduction or management of sweating in babies, then see a pediatrician or a certified lactation consultant.

Does Sweating While Nursing Indicate A Health Issue?

Baby sweating while breastfeeding is not always a cause of concern, but in some cases, excess sweating might indicate an underlying condition. The following are the possible health conditions that might make your baby sweat while feeding.

1. Hyperhidrosis

Hyperhidrosis is characterized by excessive sweating in amounts greater than what is needed to regulate body temperature (4). The exact cause for hyperhidrosis is not known.

2. Thyroid issue

Hyperthyroidism occurs when the thyroid gland makes too much thyroid hormone (thyroxine). Excessive thyroid hormone increases metabolism and may cause excessive sweating, along with other symptoms such as weight loss, rapid heartbeat, etc. (5)

Congenital heart diseases occur when a baby’s heart does not form properly during the fetal stage. It may cause a variety of conditions and disorders that affect heart function. Babies with congenital heart diseases display symptoms such as fatigue, chronic crying, rapid breathing, and excessive sweating (6).

1. When do babies start sweating?

Most babies born after 36 weeks of gestation start sweating from the first day of birth itself (7).

2. How do you tell if a newborn is overheated?

The following tips can help you understand whether or not your baby is overheated (8):

  • Feeling the back of their neck and checking whether or not it is sweaty
  • Using a thermometer to check their temperature accurately
  • The baby is being fussy

Babies sweat while breastfeeding for various reasons, including increased body temperature due to skin-to-skin contact, warm clothes, excessive covering, warm climate, or remaining in the same position for a longer time. These conditions can be managed by changing room temperature or clothing. It is recommended to seek medical care if your baby has sweating and breathing troubles, turns blue, is not gaining weight, or becomes tired from feeding. These symptoms can indicate hyperhidrosis, thyroid issues, and cardiac issues in babies, and sweating may disappear after managing the underlying causes.

Why does the baby sweat while feeding?

Bulavina Ekaterina Borisovna

pediatrician of the 1st category

The baby sweats during feeding, so much so that you have to change the vest. What is the reason for the increased sweating of newborns, why does the child sweat if it is not hot and there are few clothes on him? Everything is individual. Read about the causes of sweating during feeding and what to do to help the baby in an interview with pediatrician Ekaterina Borisovna Bulavina.


— Ekaterina Borisovna, what does the baby's sweating during sucking mean?

- All children sweat. Distinguish between normal and excessive sweating. Moderate sweating during feeding is considered normal and is not a cause for concern. But it should not be accompanied by a bluish coloration of the face or nasolabial triangle, the appearance of cold sticky sweat flowing down the face or back. The normal act of sucking is usually not accompanied by the baby's anxiety, shortness of breath with retraction of the intercostal space, pronounced palpitations. Otherwise, you should immediately consult a doctor.

- Does age affect sweating?

- Sweat glands are activated at the age of one month. Up to five or six years, the formation of the function of thermoregulation occurs. During this period, maximum sweating is observed. The second peak of sweating is adolescence, when sex hormones turn on.

- Intensive sucking can cause sweating?

- The act of sucking a breast or a bottle is work, especially for a baby in the first months of life. Therefore, even slight discomfort can increase sweating during feeding. Also, the child can spend more energy due to some features of the anatomy of the mother's breast. And even a child's posture is of great importance - if the child is uncomfortable and has to strain all the muscles, he will sweat.

— Almost every mother notes that a newborn's head sweats when feeding. What parts of the body are still sweating?

— During suckling, the baby does a colossal work, which involves the muscles of the head, neck, upper shoulder girdle. Therefore, it is these areas that are normally sweating during feeding. With imperfect heat transfer, the palms and feet of the child can sweat a lot, since a large number of sweat glands are concentrated there.

— Frequent sweating of the head and the development of childhood rickets — interrelated processes?

- Sweating combined with nape baldness often worries parents. This is the most famous symptom. But it is worth remembering that the hair on the back of the head is wiped normally in healthy children, especially until they have learned to sit, and they turn their heads very actively.

  • Common sleep problems in infancy, what ways to try to calm the baby and fall asleep after feeding.

Early signs of rickets


  • restless behavior, startling from sudden sounds, flashes of light;
  • sleep disturbance, shallow sleep with awakenings;
  • sweat clammy with sour smell;
  • itchy skin;
  • rubbing the back of the head against the pillow and baldness.

The most informative:

  • compliance of the margins of the large fontanel;
  • muscle weakness;
  • protruding tummy.

At risk of developing rickets are large formula-fed babies who rarely walk outside. But for early detection of rickets, it is enough to visit a pediatrician in a timely manner: an experienced doctor will easily notice the signs of the disease.

— How can parents distinguish external causes of sweating from health problems?

— When excessive sweating occurs, the first step is to review the surrounding microclimate. If the room temperature exceeds +25 ° C, and the air humidity is more than 60%, the child simply overheats. The next step is to evaluate the clothing: too tight, made of synthetic fabrics and needs to be replaced.

Warning symptoms requiring immediate medical attention:

  • lethargy, weakness, fatigue or, conversely, excessive excitement;
  • restless interrupted sleep;
  • poor weight gain, poor appetite;
  • lag in psychomotor development;
  • muscle weakness or, conversely, pronounced muscle tone;
  • cyanosis (cyanosis) of the nasolabial triangle during sucking, cyanosis of the extremities;
  • fever;
  • signs of a viral infection, pustular skin lesions;
  • pathological impurities in the stool;
  • prolonged cough;
  • enlarged lymph nodes of any localization;
  • softening of the edges of the large fontanel, change in the shape of the skull;
  • Distended protruding abdomen, tendency to constipation.

Characteristic signs that also require immediate attention to the pediatrician:

  • specific smell of sweat;
  • clammy, cold sweat;
  • profuse sweat in large drops, acting on the forehead, back;
  • profuse (suddenly released in large quantities) sweat, requiring dressing.

In addition to external factors, the general condition, activity, sleep, mood, level of development of the child are assessed. Moderate sweating in general well-being is rarely a sign of a serious illness - this is a temporary inconvenience that will pass with the maturation of the nervous system. Physiological sweating most often disappears with the normalization of the temperature regime, the correct selection of clothing.


— Ekaterina Borisovna, what should parents do if the baby sweats a lot during feeding?

— To make the feeding process as convenient as possible, it is necessary to create optimal conditions for the child:

  • feed in a cool, well-ventilated area;
  • dress the child appropriately for the ambient temperature in natural, breathable clothing that is loose and free of coarse seams;
  • a sleeping child should wear one more layer of clothing than an adult who is feeling comfortable at that moment, and one less layer for an actively moving child;
  • do not wear hats, caps during feeding, as the baby's head often sweats, and an additional layer of clothing will increase overheating;
  • feed in a reclining position, supporting the upper shoulder girdle with a hand or placing a special pillow; it is impossible to support only the head, since only the neck is bent and it is inconvenient for the baby to suck;
  • use special silicone pads on the nipples, knead and strain the breast before feeding in case of anatomical problems in the mother that make sucking difficult;
  • bathe the baby more often, use contrast baths or douches after bathing in cool water - hardening always has a beneficial effect on the autonomic nervous system and immunity;
  • more often leave the baby without clothes for air baths.

In addition, bottle feeding should be carefully considered:

  • use an anti-reflux bottle with a medium hard teat;
  • The opening on the nipple must be appropriate for the age of the baby;
  • Too soft or too tight nipples are not suitable for normal feeding.

Young children tend to sweat, which is associated with the imperfection of the thermoregulation system. The baby is very dependent on the ambient temperature and easily overheats. Even seemingly insignificant muscle work during sucking is a serious burden for the baby and is accompanied by the release of sweat, especially in conditions of high temperature and humidity. If sweating is excessive and the child suffers from it, this is an occasion to visit a pediatrician to determine the causes.

* Breast milk is the best food for babies. WHO recommends exclusive breastfeeding for the first 6 months of a child's life and continued breastfeeding after complementary foods are introduced until the age of 2 years. Before introducing new products into the baby's diet, you should consult with a specialist. The material is for informational purposes and cannot replace the advice of a healthcare professional.

"Why does a child sweat a lot during sleep and feeding?"


In our “Ask an Expert” column, reader Olga asks:

“A 3-month-old baby periodically sweats heavily on his head, especially during breastfeeding or when he sleeps. What is the reason? Is it dangerous?

- When a baby suckles, he experiences physical exertion, so the back of his head may sweat. This is a variant of the norm. In the crib, during sleep, the baby may sweat if he is hot. You need to check whether the mattress is too warm, whether it is hot in the room.

Sometimes parents put a pillow under the child's head that does not allow air to pass through, this can also make the head sweat.

The temperature in the room should be around 22-23 degrees, it is important to cover the crib with the right linen.

Do not forget about the humidity in the apartment. If batteries and heaters that dry the air are turned on, then we recommend placing special humidifiers in the room where the baby grows.

If comfortable conditions are created for the child, but the problem persists, then you need to be alert. As a rule, increased sweating provokes a lack of vitamin D. It is very important to control its level.

Night sweats can also be a problem in adults. In what cases should you see a doctor? Read more in the article: "From Menopause to Cancer: 7 Possible Causes of Night Sweats"

In the program for optimizing the feeding of children in the first year of life, it is prescribed: each child from the age of 1 month should receive vitamin D in a prophylactic dose of at least 1000 units during the first year of life.

Prophylactic dose given without testing. If a child develops sweating, especially of the feet or hands, in combination with signs of osteomalacia (compliance of the edges of the large fontanelle, skull sutures), then doctors suspect that the child is not vitamin D enough. In this case, they prescribe a blood test for the content of 25 (OH) D (vitamin D) and, based on its results, adjust the dosage of the drug.

The therapeutic dose can be up to 2000 units per day, and if the baby is premature, then higher dosages are used. Vitamin D deficiency is dangerous because it threatens the development of rickets.
