my son is 4 years and 9 months and his weight is only 13 kg....how to grow him.....

A. hi dear Your child is definitely low weight. We would expect a child of 4 yrs to be around 16 kg. A weight of 13 kg also would family within normal range. I suggest you to choose a good brand for your little one like Babyhug to choose a good brand for your little one is most trusted by mom's
