Spitting Up Milk: A Common Concern For Newborns

It is perfectly normal for a newborn to spit up milk. In fact, almost all babies will, at least occasionally, spit up some milk during or after feeding, even if they are not being actively burped. This is simply due to an immature digestive system, which will develop with time. As long as your baby is growing, thriving, and isn’t having any other symptoms such as frequent coughing or colicky behaviour, spitting up is usually nothing to worry about.

Spitting up is normal for newborns and usually harmless

Spitting up milk is a common occurrence in newborns and usually nothing to worry about. It is often simply due to an immature or underdeveloped digestive system, which makes it easier for a baby's stomach contents to flow back up into the oesophagus. This is why spitting up normally decreases as a baby gets older, with most babies spitting up less by 9-12 months of age and stopping by 12 months.

Spitting up is also often caused by a baby drinking too much milk, too quickly. This can happen when a baby feeds very fast, or when a mother's breasts are overfull. It can also be caused by a baby swallowing too much air during feeding, which can be due to a baby being distracted at the breast, or due to aerophagia (consumption of air in greater quantities than usual).

It is important to distinguish between spitting up and vomiting. Spitting up is a smooth, easy flow of liquid, whereas vomiting is a more forceful, shooting event, like projectile vomiting, and is usually accompanied by other symptoms such as fever or diarrhoea. Spitting up also normally does not lead to distress or weight loss, whereas vomiting can be a sign of dehydration.

If you are concerned about your baby's spitting up, there are some things you can try to reduce it. These include:

• Keeping your baby upright during and after feeding, and for 20-30 minutes after feeding
• Feeding your baby before they get very hungry, to avoid them taking in too much air as they gulp
• Taking frequent burp breaks during feeding
• Avoiding overfeeding, and offering smaller amounts more frequently
• If breastfeeding, experimenting with your own diet to see if certain foods are upsetting your baby's stomach
• Using a pacifier after feeding, if your baby will accept one

It is caused by an immature digestive system

Spitting up milk is a common occurrence in newborn babies and is usually caused by an immature digestive system. In older children and adults, a muscle located between the oesophagus and stomach keeps food and liquids in place. However, in newborns, this muscle is not fully developed yet, making it easier for stomach contents to flow back up into the oesophagus. This often results in the baby spitting up milk, especially if their stomach is extra full or its contents are sloshing around.

The good news is that as your baby's digestive system matures, they will spit up less frequently. By the time your baby is 9-12 months old, spitting up will typically become a rare occurrence. In the meantime, there are several things you can do to help reduce spit-up:

• Keep your baby upright during and after feeding.
• Avoid overfeeding and try offering smaller amounts more frequently.
• Take frequent burp breaks during and after feedings.
• Avoid active play for at least 30 minutes after feedings.
• If you are breastfeeding, monitor your diet closely and avoid any foods that may be upsetting your baby's stomach.
• Put your baby to sleep on their back.

It's important to note that spitting up is typically harmless and won't cause any issues with your baby's growth or development. However, if you notice any red flags, such as weight loss, forceful spit-up, fussiness, or other symptoms, be sure to consult your paediatrician.

Overfeeding and swallowing air can cause excessive spit-up

Spitting up milk is a common occurrence in healthy babies and is usually not a cause for concern. It is often due to an immature digestive system, which makes it easier for a baby's stomach contents to flow back up into the oesophagus. As a baby's digestive system matures, spitting up typically becomes less frequent and stops by the time they are 12 months old.

Overfeeding and Swallowing Air

Overfeeding and swallowing air during feeding are two of the most common reasons for excessive spit-up. Here are some tips to help reduce spit-up and make your baby more comfortable:

• Feed your baby before they get very hungry. If they are starving, they are more likely to gulp down their food and swallow more air in the process.
• Take frequent burp breaks during feedings. Burping can help expel excess air from your baby's stomach and reduce the amount of spit-up.
• Maintain your baby in an upright position for at least 20 minutes after feeding. This helps to keep stomach contents down and reduces the risk of spit-up.
• Avoid overfeeding by offering smaller amounts of milk more frequently. This gives your baby's stomach time to empty between feedings and reduces the likelihood of overfilling.
• If you are breastfeeding, pay attention to your own diet. Cow's milk and soy-based products in a mother's diet are common triggers for excessive spit-up in breastfed babies.
• Pacifier use after feeding can be helpful if your baby accepts it. Sucking on a pacifier can provide a similar comfort to suckling and may reduce the urge to spit up.

Gastroesophageal Reflux Disease (GERD) can cause spit-up to become problematic

Spitting up milk is a very common occurrence in healthy babies, and it usually won't cause any issues regarding the baby's growth or development. It happens because a baby's digestive system is immature, making it easier for their stomach contents to flow back up into the oesophagus. As babies grow older, they usually spit up less, and most will stop spitting up by 12 months of age.

Gastroesophageal Reflux Disease (GERD)

GERD is the medical term for problematic acid reflux. It is very common in young babies and occurs when formula or breast milk in the stomach backs up into the oesophagus and into the mouth. This can irritate the oesophagus and cause pain, heartburn, chest pain, and trouble swallowing.

GERD can cause more severe symptoms, such as:

• Poor weight gain
• Loss of appetite or refusal to eat
• Choking, gagging, or problems swallowing
• Irritability, particularly when it occurs with regurgitation
• Complications such as coughing or wheezing
• Vomiting of large amounts of milk
• Streaks of blood in the vomit
• Breathing problems
• Fever

If you notice any of these symptoms in your baby, it is important to have them evaluated by a doctor or healthcare provider.

Treatment

GERD in babies can be treated with medicine and lifestyle changes. Lifestyle changes that may be recommended include:

• Holding the baby upright for 20 to 30 minutes after they eat
• Placing the baby on their back to sleep
• Burping the baby more often
• Avoiding overfeeding
• Feeding the baby thick formula
• Not smoking around the baby

Consult a doctor if you notice any red flags, such as choking or coughing

While spitting up milk is a common occurrence in healthy babies, there are some instances where you should consult a doctor. If your baby is choking on spit-up milk, it is important to seek medical attention. Choking on spit-up milk can be a sign of Gastroesophageal Reflux Disease (GERD), which occurs when formula or breast milk in the stomach backs up into the oesophagus and mouth. GERD is typically characterised by red flag symptoms such as refusal to eat, crying, or arching of the body during or after feeding. It is important to have your baby evaluated by a doctor if you notice any of these symptoms.

Additionally, if your baby experiences frequent coughing or colicky behaviour, it may be a cause for concern. Coughing may indicate that your baby is having difficulty breathing, and it is crucial to seek medical attention in such cases. Colic, characterised by frequent crying, can also be a sign of discomfort or distress in your baby. If your baby exhibits colicky behaviour, it is advisable to consult a doctor to rule out any underlying issues.

Another red flag to look out for is forceful spit-up or projectile vomiting. If your baby is spitting up milk forcefully, it may indicate a condition called pyloric stenosis. This condition is characterised by the narrowing of the channel between the stomach and the gut, leading to forceful vomiting. Babies with pyloric stenosis are at high risk for dehydration, which can be life-threatening. Therefore, it is important to seek immediate medical attention if you notice any signs of forceful spit-up or projectile vomiting.

It is also important to monitor your baby's overall well-being and development. If your baby seems uncomfortable, irritable, or distressed during or after feeding, it may be a cause for concern. Additionally, if your baby is not gaining weight adequately or exhibits symptoms such as weight loss or fussiness, it is crucial to consult a doctor. Trust your instincts and seek medical advice if you have any concerns about your baby's health or development.
