A. Dear mum, what is your baby’s weight? For healthy weight gain, you should exclusively breastfeed till 6 months complete. If baby is active, alert, passing urine more than 7 times in 24 hours, gaining adequate weight at least 500 grams per month, achieving all growth milestones then do not worry.
