Oh boy, I'm hearin' ya.
Our DS is 17 mths old. He can self settle, learned by himself at 5 months but has never slept through. Ever. The people who say that if you co sleep or have a baby that self settles you will get better sleep haven't met my boy. A good night is getting up to him 3 times, a bad night.......well......I lose count & just go into auto pilot. His newest trick? Waking up around 1am & not going back to sleep until 4 or 5 am. (I've tried him napping less, napping more to fix this, cut down to one nap, nothing changes the party at night.) Oh, and I've tried giving him a comfort thing, spent money on a natural fibre bear with different textures.......nope......he'd rather hold his dummy by the teat & twirl it around. So now when I go in to pop his dummy in his mouth I've got two to find.
