The purpose of burping a baby is to help get rid of the excess air in their tummies that they swallow when feeding. Although burping is often associated with bottle-feeding, some healthcare providers recommend burping a breastfed baby every time you switch breasts. Some people find that burping at the end of the feeding also works for breastfed babies while others do not burp their babies at all. But swallowing too much air can cause your baby to spit up, be gassy, or appear cranky. If you notice these signs, you may want to consider burping.
