Hugs Fiona, that must be very distressing to watch. Hand flapping? Ah, kinda sounds spectrum to me as does him getting so worked up.
Do you have anyone around, parents or friends that could come to help until the baby is born? Alleviate some of that stress? I'm not much help, sorry.

Not so good here. Ds is losing his voice. Before it was the stutter but he's starting not to be able to get words out at all. He opens his mouth but no sound comes out. He's finding it really distressing so in turn I am too. Don't know how long it's going to take to get a diagnosis which means I don't know how long until we can get treatment. He's talking less in general, I think because his confidence is down. I'm trying my hardest to help him, to help put words in his mouth or distract him.

This is going to sound so naive, but I'm still learning. That sounds spectrum right? Obviously high functioning but asd kids do want to be able to express? He wants to desperately, he just can't.
