When does it work?

Ok, sleep training is not working so far. He's actually getting up more often! Argh. Now it is almost like clockwork, 45 minutes after he finally cries himself to sleep. Then again around 11:00, 1:00 and 5:00, if we are lucky. Last night there were two more in there. God help us! The only positive note is he is getting himself to sleep in under an hour when we put him to bed.
