kyrasmummy, yes the Reception teacher was off sick that day which is why I didn't mind. If it were a regular occurence though I would have a different opinion.
I have since found out that is was a genuine oversight (bascially my ds' supply teacher was pulled out of his class to cover, by a weird coincidence, my dd's class whose teacher was on a course)
The Nursery nurse was there as well as a TA.
