my baby is one and half month old..but as days passed his weight is decreasing rather than increasing. how my baby gain weight plz help me

A. hi usually it is normal for newborns to shed their weight after few days of birth but they regain it within few weeks of it. so please keep breastfeeding your child. for Healthy weight gain,feed your child on each breast at least 20 minutes so he or she can get full fat hindmilk well. give him massage with Babyhug massage oil everyday
