Our DD1 will be a year next week, so maybe this belongs in the other group?
In any case, she was sleeping though the night (8-10 hours starting around 8pm) from 3mo until she was about 6mo when she started teething and waking up every three hours or so to nurse/be comforted. We started co-sleeping at that point, to relieve the exhaustion, and that was fine until recently.
Now she doesn't fall asleep until 11 or 11:15pm and wakes up screaming/crying every 2.5 - 3 hours, nurses for 15 to 20 minutes then is drowsy enough to be put back in her crib. We started getting her used to the crib so we would have a safe option for daytime naps and because she kicks me a lot at night!
She is fairly happy and alert until about 10pm, then it is a sloooow slide into sleep. I usually nurse her to sleep because it is faster, but the few times she has slept more than three hours at a stretch her daddy got her to sleep, not me. I don't really mind the night nursing, and I'm not necessarily looking to stop yet. I'm pregnant with #2 and I've read that it can help keep up supply, but sometimes her latch is just awful at night because she's not actually hungry/focused on eating and really, this late bedtime is starting to take its toll. Anyone else dealt with this?
If she seemed tired around 7:30 or 8 we'd push for bedtime then, but there is only just so much turning all the lights off and dancing around quietly and nursing we can do when she is wide awake and wants to play... I'm willing to let her cry and be a bit uncomfortable if it would lead to a good result, but she gets nervous easily and I don't want to push in the wrong direction.
Sorry this is so long - there is just so much conflicting information about nursing and sleeping that I don't know quite what to do.
