I am giving 120 ml formula 5 or 6 times per day is this enough for my baby .should I increase the number of time?

A. Look if to feed your child on demand right so if your child is happy with five or 6 feet per day which is good enough if your child demands more give more than that but 5-6 feeding is good enough for the child as of now if your child is gaining sufficient amount of weight then it is no problem
