My baby is 4.5month and only on formula since birth he only take 120ml in every 3-4 hr and his weight is 6.5kg is it ok??

A. 120 ML is a very good amount of heat that your child is having at the age of five months and also I would like to tell you since you have not mentioned the birth weight of your child so I can only tell you if the birth weight becomes double by the age of 5 1/2 to 6 months then it is an ideal weekend
