Sorry about the tricky play date open. It probably wasn't as bad viewed "from the other side" as you thought - all 4 year olds have bad days but I think we read a lot into ours! We find how these things go is hugely affected by sleep and general health (often when I get very discouraged it turns out that actually DD was coming down with a cold or it's right at the end of term and she's knackered). And easier with friends they know (when DD's best friend from school comes over they kind of have a routine of games they always play a variant of so it's much easier for DD as she knows the rules and how to play). But like you I always want to keep her circle wider as even for NT kids you know friendships will go wrong now and again and I don't want to put all DD's friendship eggs in one (potentially holey) basket.
The Makaton course sounds great liv. It's amazing how different services are from area to area. I think often it comes down to just one brilliant individual delivering something really well. The parenting course we went to in Hackney was brilliant but I think it was down to the trainer more than the materials. He had an autistic sister and said he had traits himself and he just explained things really well.
DD didn't manage to do her dance class at school yesterday (I kind of had a feeling she wouldn't - she seemed less energised about it than the previous week) but her teacher came out to see me today about it and says she thinks she will if we just don't make a big deal about it which I agree with.
I think I've heard of the Iris Grace book open and I'm sure YouTube used to keep showing me videos of her (I think an advert ... but not sure what for? Maybe just the book!) Her pictures are pretty amazing. Her website says she is starting to be verbal now (I think she's 10). I found talking to a colleague whose sons are autistic (but probably more "classically" autistic than DD) that although they are very different you can see a lot of threads that join them: the underlying things they find stressful or difficult are the same, but they have different levels of sensitivity and express it differently.
I've just finished the first book I've read for about a year (Elinor Oliphant). I read it because I saw a suggestion the main character was autistic but I'm not sure she is (she definitely has autistic behaviours but I think a lot of those are a reaction to stress and a kind of self-protection mechanism, and autism isn't the only reason somebody would behave that way). Still, it was a good story.
I want to read the Jessie Hewitson book now, which has been sitting by my bed for a while - has anybody read it yet?
