My LO will not wear a hat anymore. No baseball hats, sun hats, sun glasses - nothing! It wouldn't bother me, but I feel like he should be wearing one in the sun. Last year he wore it no problem but this year he has decided No Way. Anyone else have this problem? He also doesn't have the fullest head of hair in the back; so I am worried he is gonna get burned. I tried rubbing sunscreen on his scalp but it turned into such a greasy mess. Any other ideas what to do?
