My son is 85cm and 15kg and he is 12months old. Is he right at his weight and height according to his age?

A. Height Seems fine it’s better than fine actually is approximately 3 feet as of now and the way it is about 5 KG app in which I would say to KG could be justified was 12 it would be good but your child is approximately 3 KG underweight on top of that also but it is also going to be justified because your child is tall so all in all I feel if I look at both the things it’s quite in proportion
