I have a little boy - he's 4 at the end of next month, and I'm just trying to get a measure of him. He's 117cm tall, and weighs 3st 13lbs - 55.4lbs.
According to the children's NHS BMI calculator that makes him very overweight, it says 98th centile but his height is way over 99.6th centilitre so I'm not sure how accurate that is? He is robust but looks in proportion.
He is very active.
I've attached a pic.
