This is the thing - all human behaviour is part of a spectrum.
IMVHandnotexpertO many toddlers have some autistic traits but most outgrow them, some don't.
I could never ever be a psychiatrist because I'd always struggle with the fact that the person in front of me is the only person on this planet who truly knows what they are feeling and you are entirely dependent on how articulate somebody is to try and tease a diagnosis and, more importantly, appropriate treatment and support out of them. Yes, you can observe behaviour, but the overlap between various MN/behavioural problems is so huge, the responsibility to get it right would send me running for the hills, screaming.
And when anything presents atypically, it's always harder to get it right
. It's part what makes medicine so hard - it's based on the sciences, but it is NOT a hard science IYKWIM.
Small talk - pfffft. I am rubbish at that.
Ok, I am off to play Yahtzee with DS1 - he's winning so far!
