DS is an only child (not for long), but likes the attention too...one more snuggle, a drink, toilet etc.... is it an age thing?! I read that you can give them a 'free pass' after you've settled them (done toilet, drink, cuddle etc) and they can get up/call you in once, but after that, you ignore all requests...straight back to bed with no interaction from you. Is your older boy awake through all of this? Does he ignore whats happening? I agree that calming music or stories might help...even just on a CD player, so he's got something to listen to and therefore doesn't need distracting. DS has lullabies on his monitor that play for about 15 mins.

A reward chart for staying in bed, not calling out, being quiet or whatever you need from him? Our DS gets up in the middle of the night and, after four plus months of 3-6 wake ups a night, we've had four nights in the past two weeks of getting up once or less. The first night was a fluke, but once we got one night, others have followed as he really wants the sticker (and the reward that goes with a certain number of stickers).
