She could also be a bit more open about her expectations - expecting you to read her mind, and then pouting about it, won't work, especially if she knows you're autistic.
Btw 4 year olds aren't easy to handle and it's usually easier for women to handle children of any age. I don't get how she expects you to be an expert in such matters.
I've had similar situations too many times which might explain my slightly bitter attitude towards that matter. People should elaborate on their expectations and not pout once they figure out we're not telepathic.
If she won't show any understanding towards your issues, perhaps YOU should show some compassion towards yourself, you deserve it.
