Night weaning a co-sleeper (14 MO) - any experiences?

[RockabillyKitty]

My DS wakes every 1.5-2 hrs a night from going to bed but it hasn't been too much of a problem as I've always fed him back to sleep. Other than teething times and the odd random thing, it has worked fine, quick feed and he's happy and back to sleep. But now that I'm at work and not breastfeeding as much in the day, my milk supply has gone down and I don't have enough sometimes to get him back to sleep in the middle of the night. So while I'm happy to continue co-sleeping I'd like to get him off the boob, or at least get him to go longer in between waking up so there's a chance for my milk to re-stock.

However, my DH suspects that while DS still has unlimited access to me, he'll still wake up as often, so it's a bit of a vicious circle. It may be that we involuntarily end up doing the mildest version of sleep training because if he doesn't go back to sleep on the boob, he ends up being awake for an hour or two at a time because he's got himself that upset we have to walk/rock him to sleep anyway. The Dr Jay Gordon suggests feeding but not letting them fall back to sleep on the boob, and instead comforting them with talking/stroking/patting in the bed - not sure my forceful, 98th percentile, boob monster will tolerate it without practically beating me up! Anybody had any experience with this?
