15 month DS wakes most nights, usually 1/2am and can only be comforted by leaving cot for breastfeed. Has to then fall into a deep sleep and be transferred back. Goes off to sleep fine at night by himself and naps well in the day. We try to feed him up before bed in case of hunger. Pretty sure he's warm enough. Shares a room with sibling so difficult to keep him in cot instead and offer comfort in room as he goes bananas if not given a cuddle.
Do I put up with it and hope his sleep matures? Or do I do something else? If so, what?
