Preventing Baby's Spit Up

If your baby is anything like my son, you probably have spit up somewhere on your clothes at every moment of the day. My son has been spitting up excessively since he was born and at 9-months-old it’s finally slowing down. If your baby is spitting up too there are some things you can try to relieve baby’s reflux and hopefully keep your clothes cleaner too!


About half of babies spit up regularly, so don’t worry, your baby isn’t alone! There are many factors that make reflux normal in young babies.


  • Young babies are still developing their digestive system. The muscles that control whether food stays down is still underdeveloped. This can cause baby’s food to come up regularly.
  • Babies are often laying on their backs which can make spit up common.
  • Overfeeding is very easy with young babies. Their stomachs are small and they may want to eat more than their systems can handle. This can cause spit up too.
  • Air can also cause spit up. Gas bubbles become trapped in baby’s food and causes reflux.

 Though much of the issues with spit up have to do with baby’s development, some factors can be addressed.


  • If you’re breastfeeding you may be able to change something in your diet to help baby with reflux. Talk to your pediatrician about what you may try eliminating.
  • Since lying flat can cause spit up, try holding baby upright during their feeding. BlueSmart mia is a bottle sleeve that can help you angle your bottle correctly when trying different ways of holding baby during feedings.
  • Keep baby upright for at least 30 minutes after feeding. You don’t want to jostle baby too much with play time but you can try sitting baby up and doing low movement activities like playing peek-a-boo, reading a book or singing songs. You can also put baby in a carrier so you can get some things done!
  • Your baby may be getting gas bubbles in their belly by eating too slowly or too quickly. Check the nipple hole size on your bottles to make sure it’s an effective flow for baby. With my son, he quickly moved on to the highest nipple flow but it’s different for every baby. If the formula or pumped breastmilk is coming out too slowly baby can develop gas. Bubbles can also occur if baby is swallowing liquid too quickly. BlueSmart mia can help you learn if your baby is feeding at an adequate pace.
  • Be careful not to overfeed. If baby is having extensive issues with spit up you can try lowering the amount of milk in the bottle or shortening the amount of time on the breast. Then increase the number of feedings to compensate.
  • Burping can help get rid of some gas bubbles that develop during feeding. You can burp baby after feeding but you can also take a break to burp during the feeding if baby naturally slows at any point. For ideas on different methods of burping check out this article.
As a mom who has been there, I understand the worries that come along with constant spit up! I had my son checked at the pediatrician and that’s something you can do too. However, my pediatrician said he would grow out of it and that spitting up is normal for many babies. I can say that at the 9-month mark I think we are finally past the all spit up phase! Hopefully these tips will help give your baby some relief too.
