My dd is 26 months and we have just moved her to a small bed as her cot is needed for her sister (5 months).
Up until 3 weeks ago she was a brilliant sleeper - went into her cot wide awake at 7.30pm, played quietly and then fell asleep until around 7am.
She was quite excited about her bed and was fine in it for a week, but the last 2 weeks have been appalling! She goes through the usual routine of bath, milk, stories etc and then as soon as we leave her room she's up out of bed and yelling at the door. Because I recently sang Baa baa black sheep for her until she fell asleep (she woke at about 3am) she now demands this at the top of her voice.
We've tried some kind of controlled crying but have to lock the bedroom door because she gets out of bed immediately. she's in a sleeping bag and has a cot rail so nothing stops her! I don't like locking the door, but otherwise she wouldn't even be in the room, and there are stairs just outside her bedroom. The other night she stayed yelling until after midnight with me or dh going in every 25 minutes or so. She stops yelling as soon as we go in and is happy to get back into bed by herself, but as soon as we make to leave she starts up with yelling again.
The last few nights we've given in after about an hour because I just don't think that her standing at the door and yelling is going to allow her to fall asleep. She could go on indefinitely!
Is there some kind of miracle solution, or should we return her cot and put dd2 in a travel cot for a few months? DD1 does seem to like the bed, she's not having nightmares, doesn't mind the dark, and hasn't had any other big changes recently. It just seems to be the fact she can get out of bed that's made her not able to sleep.
Any advice? Thank you!
