The nursery DS1 goes to is very strict about his time - He is not allowed in a minute before 9.00 am. His teacher told me in (I thought) quite a nasty way that he had to wait outside when on the one occasion since starting last year, we arrived about 10 mins early. I offered to stay with him ( all the NT children were in the room) but she said no we had to leavea and wait outside. I know they are technically in the right as he is only entitled to 2 1/2 hours a day but why make such a big issue out of it? I would never expect to regularly drop him off early and quite often when I go in at 9.05, his 1-1 teacher isn't there or is busy with another child.
