Today we were at Babies R US, and a 4 year old boy at the cash, turned to his mother and said "Look mom, she has no hair". The good thing is that he said "she" ;). The boy turned to his mother and asked why? The mother shrugged her shoulders and looked at me first to get my reaction and when I nodded ok, she then told him he could to ask me.
I have volunteered with older children before and they described it to each other as me being allergic to my hair. It seemed to work nicely for them, but obviously not with a 4 year old. So I am curious to know how do others explain their alopecia to very young children who are curious?
