I was still co-sleeping with LO at that stage. LO went into a toddler bed in our room at around 18 months old but still fed a couple of times in the night. A few weeks after she turned 2 I night weaned her using Dr Jay Gordon's method. It was incredibly easy so I think it would have worked when she was younger too, although I'm not sure about a 12 month old. Maybe worth a try though as it is pretty gentle and you can use it once they turn a year old I think, if you want to night wean anyway. After about a week of not feeding her at night (well, between 11.30pm and 6,30am), LO started sleeping through. Once that was the norm, I started feeding her on the odd occasion that she does wake e.g after a nightmare and it hasn't made things regress.
