my 3 years old baby skin colour become low I got to noticed from few days ... is it normal??

A. Child is having more exposure to the sun as in that case only you can see this kind of a thing so I would advise you to use a sunscreen lotion whenever you’re taking your child out which is what is going to be beneficial and as of now you can apply potato juice on the face or on the body leave it for a while and clean it do it every three days that is going to be good to reduce down
