my baby boy low birth weight 2.kg present 2 months completed but baby weight 3kg only. baby weight gain tips please

A. You don’t need any baby weight gain Tips because your child is gaining very well look I will explain you how we normally calculate is about 4 to 500 g again in a month right so your child was born 2KG into months for child 3 KG so if you are roughly approximated is 500 g in a month which is going very well right now
