In no hurry, but felt perhaps I should show him alternatives, in the same way I offered him solid food at a particular age, but left it up to him whether to eat it, made the potty available etc. He's bound to need some prop or change of routine at bedtime to be able to stop. I'm not to keen on cuddly toys, at least I can't get lost, but there are some around, so maybe he'll choose one as his prop himself! I'm probably thinking too much about it, he's probably old enough now to simply ask for a drink of water in the night if that's what he wants!
Have you got the baby Pantley book Luvaduck? The ideas are pretty similar, with the gentle unlatching, pressing on chin, but
before starting you create a phrase for all done nursing, which you use loads at the end of day feeds. Then you stop them falling totally asleep on the breast if they wake at night, do the unlatch when stop actively feeding, move boobs away quickly, if fussing repeat process at 30sec - intervals until falls asleep with patting.Once they are accepting falling asleep without being on breast then whisper the all done phrase. She reckons when they start to fall asleep without boob in mouth they also start to wake less for it. This was true for us, but it was before he was a determined toddler!
We moved our DS into his room at 16 months as he started waking loads again, seeming cross to be awake and not always wanting much milk. I think we started to disturb him, so we tried him in his own room and it worked. I was the most upset about it, he didn't bat an eyelid! I couldn't sleep without hearing his breathing the first few nights. I would have rather kept him in our room for longer, but it wasn't working anymore. Perhaps if will be moving him when have a new baby, could try now, especially since you don't want him waking more when you start babymaking !
