it was obvious from the topics roughly what kind of costume would be needed
But why do they need to dress up for every single thing, multiple times in a term? And how do you know when exactly they will be dressing up?
As for Christmas, we had about 6 weeks notice for our nursery play but one year it was a "Christmas story" theme and the next year a "Father Christmas and the reindeer" theme and even within those your child could have been a sheep, an angel, a shepherd or a reindeer, an elf or a child receiving presents. So if you only had a week's notice even if you already knew there would be "a Christmas play" then again, what are you supposed to do?
Limit the number of dress up days, cake bakes, whatever to one a term. It won't effect anyone's KS2 scores I promise you.
Yes, this. Absolutely.
Before requiring attendance by parents to anything, ask yourselves, is this really necessary?
And this. This is one thing that our nursery IS very good at. I can imagine that some school-based nurseries follow more of a school pattern, but we have the Christmas play (only for 2y+, and with one Jan birthday we got away with it when DC1 was nearly 2) and a "graduation" ceremony (I suspect that DC1 would be more than a bit fidgety during this and I also suspect that we may be away that day). So that's two events a year, and one of them is only for the oldest children, and the other is nearly at the end of the working day (4.30 pm I think).
A nice nativity once a year for EYFS, a concert for the older children, a single sports day, and a leavers' assembly. All with an evening alternative (except sports and the single assembly for one year only). Job done. Everyone's parents, pretty much, can make it to school for one of the two events each year and almost everyone for the assembly.
There are a couple of things at our nursery that children are invited to but must come with a parent if it isn't their regular day, for the sake of ratios, but DC1 has always managed to be in on that day apart from a couple of things that are not that exciting (a "Christmas Dinner" I seem to recall), and DC2 is too young to notice.
