As above, really. My 15 month old ds hasn't been a great sleeper for a while. He actually doesn't seem to need that much sleep - 15 mins of an afternoon and he's still chirpy until bedtime, when he doesn't want to go to sleep. Due to illness, camping and staying in other peoples' houses over the past few months, we've got into the habit of walking him around to get him to sleep, though can only put him down when he's actually asleep as even 'extremely tired but awake' results in him waking up and screaming the place down. He occasionally goes through until 3-4am when we've got him off, but mostly wakes before that and is awake on and off during the night. We do a combination of bf and walking him around during the night - sometimes he is really awake.
I'd be up for sleep training, but he shares a room with his 3 year old sister. We've only got 2 bedrooms, so no choice.
I've been trying to get him to sleep for well over an hour now and he's screaming as I type this. He's been at nursery all day - had a short nap - but is obviously tired. His sister is currently asleep in our bed, and I'll decant her later.
I know we got into bad habits when he had croup etc, but what the bloody hell do we do now?
