#asktheexperts my daughter is 13kgs.all of them telling she is lean but she is very active. do I have to worry about her

A. Actually as per normal standard child should be somewhere around 17 as of now your child is 4 kg under weight that definitely a matter of concern which is why your child is looking more lean so you should increase the intake of protein and check with your doctor if you can give any supplement to increase the muscle mass of your child
