To think that teacher should make sure 4 yr old has a drink?

OK, DS just started school, had 7 half days and then started full time this week.
All the children have to take a water bottle in, and as DS won't drink anything else, this isn't anything unusual for him. However, he always needs to be reminded to have a drink as he won't stop playing etc to have one unless he is absolutely desperate.
I quickly realised that he wasn't drinking very much and put a note in his home to school book (the messaging system). TA wrote a note that she would encourage him to drink plenty.
Today I picked him up to find he hadn't had anything to drink from his bottle at all. He said he had had one drink from the water fountain, but nothing else, not even at lunch time. I waited to speak to the teacher and she just said, "Well I remind them to have a drink, I can't check individually".
Now I realise he has to learn to drink more, but I am so, so cross that he has gone a whole day at school without a proper drink - his bottle is transparent so it's not like you can't see.
AIBU? If it continues what can I do?

IN some schools though - particularly overcrowded ones, like ds went to (children were taken out in groups every day to try and avoid breaking the law on class size) there are pitifully few staff, the adult to child ratio is crap, and ds regularly ate none of his lunch and had none of his drink. ALL day. He also got his head smashed against the ground by a group of fellow 4/5yos, because the supervision wasn't adequate (no one told me, and until it was investigated the following day I don't think even his teacher knew)

Not every school is like this. At our present school there are two TAs and one teacher for 30 children - that works. At our old school, there were two teachers and one TA I think for 90 children.

You can quite see how these things happen. I don't regret taking him out for one moment - it was complete chaos. But they expected the children to cope with it and some just couldn't. End of. (outstanding school btw)

Sorry, 60 children. Not 90 - that would have been pushing it.
