A baby no longer needs to be burped at the age of approximately two to three months. By this age, a baby typically is able to burp on his own.
Another burping milestone occurs when a baby is about three weeks old. Before three weeks of age, a baby typically needs to be burped when halfway through a bottle of formula or halfway through a breast-feeding session. At approximately three weeks of age, a baby normally is able to finish a full bottle or complete breast feeding without being burped midway through the process. Many mothers burp a baby when switching breasts during a feeding.
