What is this baby spitting up? (Baby Spit-up)

"Spit-up" is when a baby's stomach contents come back up into the throat during the first few months of life. Since babies' main food is either breast milk or formula, this spit-up is usually white. But sometimes it looks like curdled milk.

There is a good reason for this. Imagine, if a baby spits up some milk right after drinking it, it looks like regular milk. But if you spit it out a while after drinking it, by then the milk has mixed with the baby's stomach acid. Just like when we put some oranges in milk, the milk curdles, the stomach acid makes the milk curdle. So, it is not something to be afraid of if it comes out like curdled milk, it just means that the milk has been in the stomach for a while.

The most important thing is to know the difference between "spitting up" and " vomiting ." Spitting up is a slow, gentle act. It falls to the floor close to the baby's body. But vomiting is a forceful, piercing act. It can be a sign of illness. If your baby is vomiting, see a doctor immediately.

Why do little babies spit up milk like this?

The main reason for this is that babies' digestive systems are not yet fully developed. Simply put, there is a muscular ring that acts like a gate between our food pipe (esophagus) and our stomach ). We call this the lower esophageal sphincter (LES). In adults, this gate is tightly closed, so the contents of the stomach do not come back up.

But the LES muscle in young babies is not yet strong enough. So, when the stomach is full after drinking milk, this gate may not close properly and some milk may come back up. Also, babies' stomachs are very small and fill up quickly.

Many times, parents think that their baby is leaking a lot of milk. When they see a little milk spilled on the floor or a milk stain on their clothes, it looks big. But in reality, the amount that comes out is very small. Imagine, if you pour a tablespoon of water on a table, how big it looks when it spreads out. That's how it is with this.

Ways to reduce baby spitting up

If your baby is constantly spitting up milk and you want to reduce it, you can try some of these things:

  • Breastfeeding position: When breastfeeding, feed your baby in an upright position with his head slightly higher than his body.
  • Feed little by little: Instead of feeding a large amount at once, feed smaller amounts more often.
  • Burping : After and during feedings, hold your baby on your shoulder and gently pat their back to try burping. This can help release some of the extra air in the baby's stomach and reduce milk letdown. However, some studies have shown that burping can actually increase milk letdown in some babies. So, do what works best for your baby.
  • If you are formula feeding: If you are formula feeding your baby, this condition may improve when you switch to another formula. But be sure to talk to your doctor before doing so.
  • If you are breastfeeding: If you are a breastfeeding mother, be a little more careful about what you eat. Some mothers have found that when they eliminate milk and dairy products from their diet, their baby's milk production decreases. Talk to your doctor about this as well.

Very important: If someone tells you to turn your baby to sleep on their stomach because milk comes up, never follow that advice. Always putting babies to sleep on their back is essential to protect them from the dangerous condition known as Sudden Infant Death Syndrome (SIDS).

When should you see a doctor?

Most of the time, baby spitting up is normal. However, in some cases, it can be a sign of a serious medical condition. So, keep an eye out for the following symptoms. If you notice any of these, see a doctor without delay.

Some babies can develop a condition called gastroesophageal reflux disease (GERD). This is a bit more serious than normal reflux. If left untreated, it can lead to complications.
