I am ashamed to admit (gulp) that i use to do this as a child, but to the pass out stage (i dont remember thou )

Mum took me to the Doctors and was told (like others have mentioned above) that it is a attention seeking behaviour. She was told, as heart breaking as it is, to ignore it. I use to pass out and then when i came around, and got u, Mum would gie me a cuddle, apparently it stopped soon after i stopped getting the attention when i was doing it.

Can you make before bed time routine fun, with a story with that he choses so that he doesnt get so worked up and avoid the 'sleep' word... im sure you would be able to get a book about happily going off to bed, maybe you could make up a story about the fun of going to bed and make a book together?

I hope it gets better for you, Mum said it was one of the most heartbreaking thinks that i did, luckily it was short lived

HTH
