I have a toddler with the most gorgeous long hair nearly down to her bum. But every morning we have a battle with the brush because she tosses and turns around and sleeps on her back which causes massive mats / birds nest effect on her hair. Is there a solution for helping with this? If I tie it up is makes it worse because the hair mats around the hair tie and I have to cut them out. I've heard about silk shower cap type things for adults to protect their hair but I doubt that she'd keep one on and also that they even make one in her size - she's got a very small head.
Any tips or tricks??
