Spitting up in babies: What's normal, what's not

Spitting up is a rite of passage for many babies. Here's what to do about it — and when spitting up might signal a more serious problem.

By Mayo Clinic staff

Does your baby spit up after every feeding? Although it's messy, you probably don't need to worry. Spitting up rarely signifies a serious problem. As long as your baby seems comfortable and is gaining weight, there's little cause for concern.

How infant reflux occurs

If you keep a burp cloth within reach at all times, you're in good company. About half of all babies experience infant acid reflux — or gastroesophageal reflux — during the first three months after birth.

Normally, a valve (lower esophageal sphincter) between the esophagus and the stomach keeps stomach contents where they belong. Until this valve has time to mature, spitting up may be an issue — especially if your baby eats too much or too quickly.

Minimal spitting up doesn't hurt. It isn't likely to cause coughing, choking or discomfort — even during sleep. Chances are your baby won't even notice the fluid dripping out of his or her mouth.

Spitting up tends to peak at age 4 months, and most babies stop spitting up by age 12 months.

What you can do about it

To reduce spitting up, consider these tips:

  • Keep your baby upright. Feed your baby in an upright position. Follow each feeding with 15 to 30 minutes in a sitting position. Hold your baby in your arms, or try a front pack, backpack or infant seat. Avoid active play and infant swings while the food is settling.
  • Try smaller, more frequent feedings. Feeding your baby too much can contribute to spitting up. If you're breast-feeding, limit the length of each nursing session. If you're bottle-feeding, offer your baby slightly less than usual.
  • Take time to burp your baby. Frequent burps during and after each feeding can keep air from building up in your baby's stomach. Sit your baby upright, supporting your baby's head with one hand while patting his or her back with your other hand.
  • Check the nipple. If you're using a bottle, make sure the hole in the nipple is the right size. If it's too large, the milk will flow too fast. If it's too small, your baby might get frustrated and gulp air. A nipple that's the right size will allow a few drops of milk to fall out when you hold the bottle upside down.
  • Thicken the formula or breast milk. If your baby's doctor approves, add a small amount of rice cereal to your baby's formula or expressed breast milk. You might need to enlarge the hole in the nipple to make sure your baby can drink the thickened liquid.
  • Experiment with your own diet. If you're breast-feeding, your baby's doctor might suggest that you eliminate dairy products or certain other foods from your diet.

Also pay attention to your baby's sleeping position. To reduce the risk of sudden infant death syndrome (SIDS), it's important to place your baby to sleep on his or her back. If this seems to aggravate reflux, it might help to slightly elevate the head of your baby's crib — although this can be difficult to maintain if your baby moves around in his or her sleep. Placing a baby to sleep on his or her tummy is rarely recommended to prevent spitting up.
