Hiccupping is extremely common for newborn babies. Repeated bouts of hiccups generally rapidly decrease with age and often disappear by the time a baby is 6 or 9 months old.
A baby may get hiccups after a feed or bring up a little milk. He probably has reflux, but it should not bother him too much. Babies get reflux because the muscular valve at the end of the food pipe, which acts to keep food in the stomach, has not developed properly yet. This can cause him to hiccup and bring up small amounts of milk (possessing). If he has a more severe case of reflux, he may even vomit.
Reflux is normal and as long as the baby is otherwise well, one need not worry. Both formula-fed and breastfed babies can have reflux. Always have a tissue or muslin cloth at hand after a feed. Feeding the baby in a more upright position and holding him upright for up to twenty minutes after each feed may be helpful. Mothers may pat the baby’s back to get rid of the extra wind from the baby’s stomach through his/her burp.
