...but I'm really sensitive about the bald spot of the back of my daughter's head! She does not spend long periods of time on her back or in her carseat and for awhile I couldn't figure out WHY she was losing the hair on the back of her head. Then, last night when i peeked in on her before I went to bed, I noticed that she was rubbing her head back and forth IN HER SLEEP! I'm not sure what to do. I put her on her side for her naps but at night, she sleeps on her back. We're working on having her enjoy tummy time more and she's quite independent - she likes to lie on her play mat and kick or smile at herself in the mirror. Any advice? Anyone else know what to do about the bald spot? When will it go away??
