my baby girl vihana age- 3 months5days birth weight- 2.3kg present weight- 4 kg completely on formula feed I am too much concerned about her weight.Is her weight OK ? If not then what should be do ?

A. Practically Child has gained 1 1/2 kg in three months which is practically okay because it is said that if a child is gaining a minimum of 400 g to 100 g every month after birth then that’s considered a healthy ideal weight gain so if your child has gained about 1500 g so would say it is quite a good weight gain
