Hi dear Neelam,
Your son appear to have blephritis.(part of dandruff
). Shampoo the scalp
hairs twice weekly with some antidandruff shampoo .And also clean the eyelids repeatedly with diluted soda bi carb solution or lids can be cleaned by some babyshampoo which is nonirritating to the eyes.
Hope this will alleviate the problem of your child.
