I have 3.5 yo and a 16.5 month old DDs. The oldest sleeps through the night, and has pretty much since she was 18 months old. She is a very sound sleeper, like my DH. The little one is a terrible sleeper. She coslept until 11 months, when she became a kicker, but transitioned well to her crib. I nurse her in the beginning of the night and put her down awake. She can put her self to sleep most nights. She will sleep for 3-4 hours, then the fun begins. She starts waking every 1.5-2 hours. She is a screamer, she gets downright hysterical if we don't get in there fast enough or do what she wants. I've tried starting nightweaning, sending DH in there to cuddle with her, but when she wants me, no one else will do.
My question is, do you have children that are (were) this age who sleep in the same room? Does having a sibling there help the other child sleep? Do you think it would disturb my eldest to have her sister in there waking? Like I said, she's a very heavy sleeper. We've vacationed before and all slept in the same room, and she slept through her sister waking (this was when we were still cosleeping though, so it wasn't as loud). I'm desperate for sleep, and I'm hoping for any solution. The girls get along very well, and I know they won't be playing at night (we'll put the little one to sleep first). Is there any way this could help her sleep, or am I just so sleep-deprived that I'm delusional?
