I'm at the end of my tether. My 20 month old daughter who used to go to bed awake in her cot and then sleep for at least 12 hours, has suddenly refused to go to sleep unless I'm in the room, singing, holding hands etc,etc. Whenever I try controlled crying she gets so hysterical she starts headbanging really violently on the rail of her cot and also tries to make herslef sick as she knows I can't ignore that. It was so bad one night we ended up in casualty. Everything I've read on the subject says it's normal for toddlers and babies to head bang rhythmically as a comfort thing. I feel with my daughter it's sheer temper and attention seeking - and, interestingly enough, she only ever does it for me!!! She falls asleep immediately for babysitters! Everyone says to ignore her and she'll stop, but sometimes the bruises on her head look horrendous and I'm sure she must ne doing herself some damage. Please help!
