Sorry I can't hellp much with what to do, but I can tell you that I went to the QE sleep centre, and I ended up leaving early because I couldn't deal with listening to DS crying his little heart out. (His crying triggered my PTSD - which when I tried to explain this to the counsellor, she told me that while I had PTSD 10 years ago, that didn't mean I had it now, plus I top scored the depression (edinburgh test) - so I left early, totally disgusted with their 'prescription help'. Plus they did not listen to what I had to say about DS, being a one shot baby. I've only ever had one shot at putting him to bed and if I missed that he'd be overtired.

But they did watch DS eat, and they said that if he wasn't getting enough food, then that would cause him to be restless.

hang in there
