cat64 that's a very good post.
Actually as I observed to a colleague astonished at this, yes, chocolate is not allowed in our school either, except on friday "treat day" for snacks.
I agree with others that one good reason is that the teachers have to work with children who have had nothing substantial for lunch, or just sthg that will give them a sugar high and then resultant low - rather than slow release apple, flapjack etc.
Sorry but am rather at a child having 4 packets of crisps a day. Overweight or not, that's a lot of salt and oil and not a great message on eating all round.
Psychomum I like the sound of that lunchbox day - what a good idea!
Peachy they have chips once a month IIRC at our schools (and many others). I do think that if your child had allergies you would reasonably be excepted from a lot of these sort of rules. shrooms I wonder if you have looked at a school lunch menu lately?
Anyway, to reiterate what another poster says, the school hasn't banned cakes and biscuits to packed lunch eaters can still have a sweet treat. Just not a chocolate bar. I guess I agree it is a bit random, but I think it's about steps in the right direction. Pudding at DD's school today (I know cause I was there) was yogurt or fruit salad which is not exactly sticky chocolate pudding is it?
