Hi good afternoon I have 4months old baby boy... after delivery how to loss the weight please can any one suggest me

A. hi dear Babies are born with some extra fluid, so it's normal for them to drop a few ounces when they lose that fluid in the first few days of life. A healthy newborn is expected to lose 7% to 10% of the birth weight, but should regain that weight within the first 2 weeks or so after birth.
