you can list dislikes and they won't put those in your box

True. Though Riverford say that the reason they don't do that is because it minimises waste...

I'm impressed you don't let the kids drink anything except water (out of interest, are they allowed milk? and was it easy to get nursery to stop giving them anything else?). Unfortunately Img knows about other drinks now and I think banning them would cause huge battles -- yes, I'm a hopelessly weak parent, but I really don't want to do anything that makes mealtimes unhappy. Besides, I don't think I'm strong-willed enough to give up all non-water drinks, and it doesn't seem fair to tell her "we get to have nice drinks, you just have water" (see above re being a weak parent). :-/
