Almost all babies spit up, especially newborns. Spitting up happens less often after the muscles of the esophagus, the muscular tube that connects the throat to the stomach, become more coordinated. This process can take as little as 6 months or as long as 1 year.
When spitting up becomes a problem
If your baby starts spitting up after every feeding, there may be a problem with the way he or she is being fed. He or she may be swallowing too much air when sucking, or you may not be burping the baby enough during feedings. Fever will sometimes cause a baby to spit up. Milk (lactose) intolerance and food allergies also can cause increased spitting up. Other signs of these problems include loose and watery stools, irritability, and belly pain.
Spitting up should not be confused with vomiting. Vomiting is forceful and repeated. Spitting up may seem forceful but usually occurs shortly after feeding, is effortless, and causes no discomfort. A baby may spit up for no reason at all. Vomiting may be caused by a more serious problem, such as pyloric stenosis or gastroesophageal reflux disease. If you think your baby is vomiting, contact your doctor.
Tips to reduce spitting up
The following tips may help your baby to spit up less often. If this advice does not reduce the frequency of spitting up, contact your doctor.
If you think a food allergy may be the cause of spitting up, talk to your child's doctor about starting your baby on hypoallergenic formula.
