Hi, i have a 2 yr old daughter, she has slept through 10-12hrs since she was 4 days old and now all of a sudden she won't sleep...nothing has changed in her routine but for the last month i have to sit with her until she's asleep which i have NEVER had to do and she only sleeps a few hours and wakes up and starts crying her heart out. It seems like something has scarred her as she won't let you leave the room while she's still awake. I honestly don't know how much longer we can go on like this as we are only having 3-5 hrs sleep, i have tried everything i can think of...any suggestions? p.s she is that scarred she climbed out of her cot so we have had to take the railings off, she seems to be fine having a bed...made no difference to her sleeping though!!
