At dd's school they have water bottles in class. They are not allowed juice in case it spills because it would be sticky. They can have juice with their lunch though. About once a week XH will take her to school and always gives her juice. The school are understandably not happy and I am fed up reminding him of the rules. He is very much of the I'll do what I want camp.
Next time the school complain WIBU to tell them to take it up with him as I am fed up being made to feel like a baddie for something which is outwith my control.
