Hi, am fretting about whether or not to put in some snacks for my DS on his yr 7 residential trip - they're going up north for a 5 day trip, camping, and it hasn't said in the literature NOT to put in snacks - is it generally accepted by schools that parents can put in some snacks? I'm not talking hoards of sweets, just a few savoury snacks and maybe 1 packet of sweets! Any views much appreciated as I don't want to get him into trouble by putting in stuff he's not meant to have!!! Thanks.
