My baby spits up after every feeding. She may eat more than her stomach can hold, or it may follow a burp. Just remember that spitting up is common, and very different from vomiting. Vomiting usually happens after she's eaten, produces much greater volume, and is more upsetting to your baby. My baby always has the hiccups.
Most babies hiccup regularly after meals, especially during the first few months.
It doesn't really mean that he has a tummy ache or some sort of indigestion. About the only thing to do is check to see if he has a little air in his tummy by trying to burp him. My baby hasn't had a bowel movement for two days. Constipation is not the number of bowel movements your baby has each day. It's when those infrequent movements are firmly formed stools that are difficult for your baby to pass.
