Since moving the bassinette to the nursery we've had 7 of the last 9 nights with him sleeping from 10ish to 5am. I think he was just ready to drop that middle of the night feed anyway cause he'd done it 2 or 3 times before that. The first few times he was in the nursery I slept terribly even though he slept well. I was just so used to hearing all his noises when he slept but now we're both sleeping well. I think he'll go into the cot in the next week or 2. He was just lying in his big cot this morning after I changed his nappy and he seemed to love it, especially the mobile. He was smiling and cooing away! Thanks for the replies.
