Over the past couple of weeks I have managed to get DD to sleep on her own during the day - that's right, no more only sleeping on me. It all happened when she learnt to roll over from her back to her front just the other week. I was trying to get her to have a day nap in our bed (we co-sleep) and she was trying to roll onto her belly. I moved so she could and less than 30 seconds later she was asleep.

I now put her on her belly straight away when I can see she's ready for a sleep. 9 times out of 10 she will go straight to sleep.

The problem is when she wakes up though. I could set my clock by her in that she wakes exactly 45 minutes after going down, which is apparently the sleep cycle, but she wakes up crying. Or actually, she's not yet fully awake when she's crying. There's no stirring, just full on tears and the "meh... meh... meh" sound of being really upset. (As apposed to the squeels and general fussy sounds).

She occasionally did this even when sleeping on me, and I would cuddle and whisper "it's ok, mummies here, you're ok" and she would drift off back to sleep after a minute or two. When she's in the bed though, I can't get her to stop crying and go back to sleep unless I pick her up. Any cuddling, lying down beside her, patting, sshhh'ing etc doesn't help and she ends up waking herself up fully.

After I have picked her up she'll go back to sleep ok, but I can't put her back down again. No matter how long I leave it, or how many times I try, after that first 45 minute sleep on her own, she'll only stay asleep on me. She will stay asleep for 2 - 3 hours on me (which does get in a full movie lol) Any attempts to put her down result in immediate tears and her waking up. I pick her back up and she stops again and goes back to sleep.

What might be causing the crying? Do babies have bad dreams? Could that be it? I first thought it might be her realising she is alone, but she's not even really awake when she's crying...
