Thanks so much everyone 
In some ways it's not a big deal at all, as I have known it in my heart for a while now. To them it's pretty cool - after all they know their mummy is autistic
:o and lots of their friends are (huge proportion of the local HE community, because like the Caglets they weren't managing in school). So it's all very positive. ASD is just a different type of brain, and they will grow up proud of it I hope. :)
Mostly it's the relief that has overwhelmed me! Relief that the concerns we have are being listened to. I am not sad for them, because the label doesn't change them. :) I love how different they are, they are my kind, quirky, funny, geeky kids - but now the things they do struggle with have a name and a reason, so that's just overwhelmingly brilliant.
I am waffling now sorry, I think I will need to write a blog post about it instead! :o I haven't for months since feeling so sick.
Speaking of which, any final bets on baby? Scan tomorrow :o :o :o
