Up until a month ago, my 21 month old DS slept 7.30 to 7, with a two hour nap in the middle of the day. We're now struggling to get him to sleep by 8.30, and he's up at about 5.30 - the nap still stands. What's more, whereas we used to be able to put him in a cot and he'd look at a book until he went to sleep, he now wants me sitting next to him again until he falls asleep. I'm 35 weeks pregnant, and this is killing me.... His room is dark (though chinks of light get through), he has plenty of exercise during the day (which seems to exhaust me more than him) we have a proper bed time routine (bath, milk, songs, bed) and yet, and yet.... Please help! Any ideas welcome! (I think he's too young for a grow clock, incidentally).
