My DD is 10 months old and recently prefers not to breastfeed to sleep. She might nurse for a moment, but then she rolls over and wiggles a bit and then drifts off. I'm convinced that eventually she won't nurse at all but will just cuddle up (actually, she did that this afternoon nap). And then, eventually, she won't need to cuddle up to me but her daddy will as a comforting presence, instead. At some point she'll just go to sleep by herself. It's working out really well.
My 1st baby... I still nursed him to sleep in the evenings every night until he was 18 months old. But after 11 months I just cuddled & sang & talked to him if he woke up in the middle of the night. The first few nights of night weaning I left DH to go comfort the baby. Husbands never take crying as seriously... but DH tells me there was almost no crying.
To be honest, I'm less bothered about it all, now, with my 2nd. I reckon DD will drop me as a sleep aid when she's ready. She sometimes sleeps in our bed, usually I can shift her to her cot without a fuss. I reckon she'll get in there full time, eventually. To be honest, I just go sleep on the couch if the bed feels crowded.
I know these aren't answers for everyone... but for me, a bit of laissez faire definitely has kept me more sane than trying to feel like I had to be in control of the situation. Sometimes (like when I'm shattered and DD has nursed for more than 40 minutes at bedtime) I have left babies to cry, but it's a much more pleasant life to avoid all that.
Plus, all the extra nursing keeps my periods away. And that's such a terrific health bonus, I can put up with a bit of sleep deprivation.
