Although there is a wide range of ages at which babies stop burping, if your daughter is now 4 months old, and does fine without burping, then you likely can simply stop trying to burp her. It may be that she is just not swallowing much air as she eats anymore.
We do not know how much air gets in their little stomachs, so it is a good idea to burp the babies even if they do not get to the fussy stage, recommends Erika Landau, M.D., a pediatrician in New York City and coauthor of The Essential Guide to Baby's First Year.
