How can I get DD to go back to sleep at 4am?!

[FudgeyCookie]

DD is 14 months and used to be a brilliant sleeper. But for the last couple of months she started waking at 6am (I could cope with this!) then 5, and now 4. When she first started waking at 4/4:30 it was to get up for the day but now she just goes straight back to sleep on me on the sofa.

But no matter how much I try I can't get her back to sleep in her cot, she will literally just scream. Being up from 4am is started to exhaust me so much I'm falling asleep in the evening after she has gone to bed. I've tried putting her To bed later but she just wakes up earlier :(

This happened to me with my 1yo, used to sleep through till 6 or 6.30, now crept back to 4.45, it's killing me. I have no advice so hope someone on here can help us! I'm thinking of letting him CIO with 5 min reassurances, but at the moment he comes into my bed and watches baby einstein whilst I half doze for another 30 mins and I'm not sure I can handle the screaming, plus we have neighbours who I worry about waking at that hour.
Anyone got any ideas? Are they just early risers?

I've tried CIO with DD but she screams, not cries haha. I came downstairs with her this morning at 4 sat down on the sofa and she was straight to sleep. Dp keeps telling me to leave her but I've told him that when he gets up with her everyday at that time of day he can give me suggestions, I'm not leaving her to scream!

Just need some ideas, hope we get some!

qualified and v experienced ex Childcarer here. Is she hungry? If so, I'd try leaving her a few mins while you fetch a bottle. No lights on in her room, bum change, feed, cuddle and back in. It used to drive me insane when mums would appear back downstairs with baby after they'd wakened but not ready for them to get up (as it undid all the good work I'd put in for them.) I never left their bedroom and never had a problem. I'd also not talk at all, it stimulates the senses. If she realises she can have her needs attended to without attention it may just work...of course, what you need is a parent's advice. They do know best.

Yeah tried leaving her for a few mins while I get a bottle and done what you say about bum change etc. she will finish the bottle and 8/10 times will start screaming again afterwards. I'm at a loss I really am.

I don't want to be getting up with her at that time, but I'm also not willing to let her scream the house down when my neighbour has small baby/children as well.
