I'm concerned my baby girl is getting a flat head. She's almost 14 weeks. She sleeps in her swing during the day and a dock a tot at night. I try to keep her off her back during the day by holding her and playing with her, but she doesn't want to be held all the time. I have a floor seat but she'll only stay in that for about 20 min. We do tummy time, but that lasts maybe 10 min. I've tried to put her to sleep on her side for naps but she won't stay asleep. She's never slept on her stomach. I don't know how to keep her off her back. She turns her head both directions while sleeping, but she's got a considerable bald spot in the back of her head too. I don't go back to the dr until June 13 for her 4 month check up, but I'm thinking I should call the dr on Monday and make an appointment. Any advice?!
