my baby is 3 months old and she is born with a weight of 2.8, now she is 4.5 is this a healthy weight gain, if her weight has to be increased what should be done. Please suggest

A. 1700 g in three months is ideally very very good you should have been somewhere around a minimum of 1500 g in three months your child has gained 200 g extra that means with feeding that you are giving your child is gaining very very well
