It's normal for babies to spit up. This can happen right after feeding or a while later, often with a burp. As babies grow, they usually spit up less often.

• Burp your baby during and after feeding:
  • If breastfeeding, burp each time you switch sides.
  • If bottle feeding, burp after your baby drinks 2–3 ounces (60–90 ml).
• Don't overfeed your baby. Ask your health care provider how much your baby should eat and how often.
• Keep your baby in an upright position for 15–30 minutes after feeding time. Holding your baby over your shoulder is a good way to do this.
• Always put babies to sleep on their back at bedtime and naptimes. Your baby will not choke if they spit up while sleeping.

Your baby:

• does not seem to be growing
• cries a lot more than usual
• won't eat, or cries and arches away from the bottle or breast during feedings
• coughs, chokes, wheezes, or has trouble breathing
• has forceful vomiting more than once
• has blood in their poop
• still spits up after their first birthday

Your baby throws up blood or bile (a green or yellow liquid).

Why does my baby spit up? Spitting up is a normal part of being a baby. The muscles in a baby's esophagus (the "food pipe" that connects the mouth to the stomach) are still developing. They're not strong enough to always keep food down. Food can flow back up into the baby's mouth or nose after eating or with a burp.

Does my baby need medicine to treat the spitting up? No. Spitting up isn't painful and your baby is growing well, so medicine isn't needed. Your baby will probably stop spitting up by the time they turn 1.
