Thanks again for all your suggestions. Keep 'em coming!

So, the crappy nights continue, although we have had one small victory. Since I have added a massage and story to the bedtime routine, DS seems to have stopped waking up half an hour / hour after he goes down. So, we are getting between 2-3 hours sleep most night before he wakes up.

We have also got some nice peaceful sleepy noises/music set up in his room - tonight is the first night we're trying that out.

I also have a couple of books to work my way through.

We'll keep plugging away. Hopefully something will work/help.

Thank you again for your suggestions and support .
