I`m sure it`s much harder when you have another lo running around, wanting attention and providing destruction.
How about putting her down for a nap earlier? Sometimes if dd is OT this works, and it`s only for one day, so she can catch up on her sleep, so no need to worry about EWs.
For me, apop means have her on my chest while she is asleep (only if she is very, very upset or is sick), or stay with her while she goes to sleep in the crib, while I have my hand on her chest. Until now every time the GS or WW was over she would go back to sleeping independently.
Now she has some days when she goes back to sleep on her own, but often she needs someone in there with her.
In the morning she wakes anywhere between 3 and 7. We manage to get her back to sleep if she wakes before 6, but if she wakes after that it`s almost impossible. As Heidi said, lots of coffee.
And patience, this too shell pass.
