Spitting up is common with babies. Babies may spit up when they burp or with their drool. Spitting up should not cause your baby any distress. Most often babies stop spitting up when they are about 7 to 12 months old.
Why Babies Spit up
Your baby is spitting up because:
- The muscle at the top of your baby's stomach may not be fully developed. So baby's stomach cannot hold in milk.
- The valve at the bottom of the stomach may be too tight. So the stomach gets too full and milk comes out.
- Your baby may drink too much milk too fast, and take in a lot of air in the process. These air bubbles fill up the stomach and milk comes out.
- Overfeeding causes your baby to get too full. So milk comes up.
Spitting up is often not due to a formula intolerance or an allergy to something in the nursing mother's diet.
Spitting up is Often Normal
If your baby is healthy, happy, and growing well, you don't need to worry. Babies that are growing well often gain at least 6 ounces (170 grams) a week and have wet diapers at least every 6 hours.
How to Reduce Spitting up
To reduce spitting up you can:
- Burp your baby several times during and after feeding. To do so sit the baby upright with your hand supporting the head. Let the baby lean forward slightly, bending at the waist. Gently pat your baby's back. (Burping your baby over your shoulder puts pressure on the stomach. This might cause more spitting up.)
- Try nursing with just one breast per feeding while breastfeeding.
- Feed smaller amounts of formula more frequently. Avoid large amounts at one time. Be sure that the hole in the nipple is not too large while bottle feeding.
- Hold your baby upright for 15 to 30 minutes after feeding.
- Avoid a lot of movement during and immediately after feeding.
- Slightly elevate the head of babies' cribs so babies can sleep with their heads slightly up.
- Talk to your baby's health care provider about trying a different formula or removing certain foods from the mother's diet (often cow's milk).
When to Call the Doctor
If your baby's spit up is forceful, call your baby's provider. You want to make sure your baby does not have pyloric stenosis, a problem where the valve at the bottom of the stomach is too tight and needs to be fixed.
