Girlie I totally understand your reticence to say about SPD before a sleepover. I always worry that I'm selling my ds short if I highlight things that might not even be a problem.
From my Beavers work I feel it's always better to know what issues there might be for a child in advance. It's much easier than trying to work stuff out on the fly, or having to phone a parent and ask tricky questions about an issue that might possibly be sensitive for them as well as for the child. That just my thought though. I think it's probably a very personal thing, so may be different for you and your dd.
I'm still working hard at the music here. Ds and I can nearly play the thing that we're meant to have learned for his lesson on Saturday, and I am trying to learn a clarinet part to play with Dh.
The clarinet thing is basically because the breath control of playing the clarinet calms me right down and I want to be in good nick on Monday for my ASD test, so on I bash with the practising. Otherwise, a day off, to try to be ship shape and ready to go on Monday.
