fluffy thanks yes I have one of those lamps. It's good but at the moment it gives me a headache when I turn it on.
Girlie Yes I am hoping that he might just manage, but I'd like to have a plan in case he doesn't.
lifelong I swear by vit d too. :-)
lilac I did wonder about that and I asked the head. She said they'd notice if it was a regular medical appt, but I suppose if we had a lot of dental and optician appts they might not notice. 
It wasn't that often last term really.
Mummyshortlegz yes he's in year 2 now. I've only just found something he can eat that has vitamins added, so that's a major breakthrough. I'm really hoping that it will help.
cag Yes the moving groups thing is weird. I'm so frustrated by that. The Pediatrician says he's got an absolutely rock solid immune system as he never really gets a high temperature. Apparently that means his immune system hardly bothers to lift a finger. The assessment was just for tiredness. Even the school agrees that he's completely normal behaviourally now, so that's good.
Somebody on the health list mentioned flexi-schooling. It does sound great. The problem apparently is that they he's marked absent which again affects their statistics, though not as much as if he was actually ill. I will ask about it.
Thanks for the vitamin info Collie. That's been our big problem up to now, that I couldn't find a vitamin that he could tolerate. I have now. I still can't tolerate any vitamin supplements that I can find. I'm trying to pluck up the courage to try rice krispies myself. How tired does a person have to be before they can no longer eat rice krispies?
Thanks for all the ideas.
