Our 14 month olds twiddles her hair as comfort to go off to sleep and when feeding. This has progressed into twirling the hair around her fingers and pulling it out. Any tips on how to stop this?? We've managed to get her to stop doing it whilst feeding so it's just when sleeping! She has a teddy she sleeps with which is really soft and doesn't seem to be comfort enough and she has a taggy blanket.
