hi mam good morning, my question- my babies weight is less than the 1 kg than actual weight...now they are completed 4 months . Thank you

A. Hello good morning !! Babies gain 400-900 gm per month and by 5-6 months they double their birth weight. Check whether the baby is nearer to double of his/her birth weight then ok. Give frequent feeds every two hours,check whether the feed is sufficient,sleeping 12-16 hours a day or not.
