More than half of all babies experience infant acid reflux during the first three months after birth, according to the National Digestive Diseases Information Clearinghouse. Although infant acid reflux is most likely after a feeding, it can happen anytime your baby coughs, cries or strains. And it’s probably tougher on you than on your baby. Even when soaked in spit up, most babies who have infant acid reflux are healthy and content. Infant acid reflux typically resolves on its own by ages 12 to 18 months. In the meantime, changes in feeding technique — such as smaller, more frequent feedings, changing position or interrupting feedings to burp — can help keep reflux under control. In a few cases, medication or other treatments may be recommended.
