my son is 11 year old...and his height is 5"4 and weight is 80kg....it is normal

A. The height of your child is very good and the weight is extremely extremely high I don’t know how your child is 80 kg at the age of 11 because your child comes into the bracket of being an obese child which is extremely unhealthy you really need to work upon a diet as well as a good physical exercise which will help in reducing the weight of your child
