Babies gain weight very quickly in their first year of life and need a lot of food to do so. It can sometimes be difficult for your digestive mechanism to deal with it without any problems. Infants therefore spit up more frequently in the first few months of their lives. It is normal for a small amount of milk to come back up, about a spoonful. Rarely does belching indicate illness. But then it is usually accompanied by other problems, for example, if the child is not growing properly. Half to two-thirds of all babies burp at least once a day by the time they are six months old. So if your baby spits up more often, there's nothing to worry about: it may be annoying at times, but it's normal as long as the baby isn't having any problems. It also doesn't spit up because it's been fed too much or because it doesn't tolerate the milk well. At ten to twelve months, only 5 out of 100 babies spit up. For the others, the problem just outgrew it without any treatment. When the liquid burping stops is different for each child: Some babies still spit up regularly when they are older than a year.
