my ds2 weaned himself at 15 months we werent night feeding and hadnt been for 6 months when we night weaned i just put him in his own cot in a different room it was a week of waking up for 1 night feed each night then he just stopped waking for them, he squeezed an extra feed in the daytime though then they just gradually dropped i got pregnant when he turned 1 and by the time i was 3 months my supply had dropped quite low and he had dropped off a few more feeds so i started a "dont offer, don't refuse" and in 2 wks he had stopped asking id be offering the same drinks as ds1 was getting through the day with meals and he was fine.
