my 4 yr son has 2 grey hair..he s 20 kgs...rest he s a good active child..is this of high concern..what's could be the reason and what is the action point ?

A. At this age also your child is approximately 4 kg overweight as in if even if you take about 16×18 kg by the age of four years still your child is about 2 kg overweight so in that case it would be good that you do try to manage the weight gain of your child and grey hair are very normal these days we do not have a reversal do that
