My baby is 48 days old.His birth weight is 2.65kg and now he is 4.7 kg.is it normal gain 2.05 in 48 days.i have no breast milk using formula milk

A. yes dear weight is fine accordingly age moreover if ur child is active and healthy and playful and having his feed properly on regular intervals and passing urine properly at least eight to ten times a day then there is nothing to worry about at all u can even start with semi solid diet after few days
