My baby is 2 month old .. his birth weight is 2.935kg.. now he is 3.8kg.. is it okay .. he is on both breast feeding and formula feeding

A. Hello good morning !! Baby weight according to both age and birth weight is fine dont worry. In general babies gain 400-900 gm per month . Continue to feed exclusive breast milk or formula milk until 5 complete months and is enough ,give frequent feeds every two hours. Burp well after every feed,do regular massage and tummy time from 3+ month onwards.
