My baby is 5year old and from last 2-3 days his nape is paining whenever he looks down to do study plz suggest what I should do

A. Maam then you should check with your doctor about the pain that you are mentioning also I would say that the pain could be due to growth pain which is completely normal and common to be seen with kids in this age for that mass massaging would be a good option and also you should definitely start with calcium and vitamin D supplement for the child
