No blaming the club really, but maybe could get involved to come to some sort of solution with them given the bairns situation. I see your point about the risk it being thrown at someone. Another alternative is that they look at the catering side and provide childrens drink like fruit shoots, even if it means them being poured into one of they polystyrene cups? It's full fat coke/bru they serve, he could have bought one of them? Just kept it beside themselves incase the bairn needs it, and you don't have to worry about it going flat, because it already practically is.
