Night weaning a toddler - how long might it take?

[AngelDog]

I know the answer is 'how long is a piece of string', but can anyone tell me how long it was of your DH resettling at night before your DC got the idea that milk was no longer forthcoming (whether you did it for part of the night or all of the night?)

DS is 20 m.o. and DH wants to night wean (well, completely wean tbh :() and I don't think he has any idea what he could be letting himself in for. If I can, I'd like some real-life examples of how long / easy / difficult it was for others so we can have an informed discussion about it.

At the moment DS and I co-sleep and DH hasn't dealt with a single night-waking ever. Most nights DS only wakes once, but when teething or working on a developmental leap (like now) he can wake up to 8 times. I currently bf him to sleep and every time he wakes.

this is TSC with a name change.
we just put him down in his cot in another room, he slept- i wonder if it was us waking him up. He's gone every night, bar one,in his own cot in his own room til 5.30-6.30. the longest dp has had to do controlled crying is 10mins (he did 1 min-back in, 2 mins- back in, 4 mins- back in,7 mins- back in,asleep in the 10 min period. so less than half an hour i reckon of lying him down) he occasionally stirs, then goes back off. he didn't know how to get himself to sleep,now he does.
i've said to dp if he's teething or ill or his chest is bad all bets are of though.

MBJ, I just wanted to say thanks for recommending Mothering Your Nursing Toddler - I'm really enjoying it. :) It's helped me keep perspective recently when DS has been howling for milk in public because he gets frightened being with large groups of people or in noisy places. It's hard to be discreet about bf when you have a child who spends most of their time shrieking "Milk! Nooooooow!"

DH hasn't said anything more about weaning, and has made a few generally positive comments about bf. :) I'm going to wait till DS's teeth are all through and then suggest we discuss night weaning if my periods haven't returned, and see what DH thinks then.
