jammy, I don't think going to the cinema will harm, and it's good to have something to occupy your mind, better than sitting at home worrying. The nursery probably wouldn't contact you unless DD was ill anyway, next week you'll have plenty to occupy you, so have a bit of fun for once, DD is safe. She was probably only over-excited today, I find NONE of my boys cope well with change. I do feel for you though, it's hard to hand them over, however old they are. I don't remember ever putting DS1s name on anything except his bag when he went to nursery.
What were you going to see?
DS3 is doing lots of stinky nappies but I thought that would be the cheesy parsnip potatoes. He has been rubbing his tongue pn his bottom gum a lot today though. His bum is nastily sore.
