@Snugglemonster84 Some people say put pressure on him and challenge him, others say don't do this as this increases his anxiety? Two opposite offers of advice. When we challenge him he crumbles under pressure to learn something such as an instrument or a new skill. Both pieces of advice are true, though. He doesn't need to be "challenged" so much as taught how to meet a challenge. There are dozens of emotional and practical skills in play when a human being works towards overcoming a challenge... he needs someone to help him work out which ones he's missing, and then help him learn them.
If you simply "challenge" him he may fall apart, yes, because the skills aren't there.
@TrickOrTreaty I think it's different for everyone but for my DS, it's being very empathetic but also very honest about the impact of his choices, and also realistic about how things are going to feel. My main phrases are -
"I know you don't want to. It's horrible to not know how to do something." (Pause and allow tears or rage)
"You do need to to this though. You know as well as I do, if you don't do this homework, [natural consequence]. Do you want that to happen?"
"OK, if we want to avoid that happening, we need to x"
"You're right, it's not going to feel good."
"You don't have to like it. You can hate it the whole time. I will be here with you."
"Let's breathe together before you try."
(Rugby tackle into a hug if needed)
"I know you don't want to, it's very hard for me to see you like this, but I'm the mum and I'm in charge of making sure you learn what you need to know."
(after he has tried, at which time he is usually relieved to get started)
"I want you to know it's so hard for me to upset you like this, it makes me feel xyz when this happens"
"How are you feeling about this?"
I also have a little chart of growth vs fixed mindset, drawn up as a comparison of Jedi vs. Sith qualities, we go over that a lot when he is freaking out and negative.
When it comes to interpersonal issues like being nasty or rude, my style of pulling him up is like this:
"Darling that's bad manners to say that."
"Do you know, folk feel XYZ when someone does something like that. Do you want people to feel that way?"
"How do you want people to feel?"
"OK, if that's what you want, I suggest you act like abc in that situation. It seems like you were feeling MNO but that's not what's important when it comes to responding to that situation, you can deal with those feelings later, at the time you need to abc."
And then debrief on the feelings and how to cope with them.
Hth. It's not one size fits all. My dc is very attuned to others and does give a fuck about how they feel, if that makes sense, but you need to find each child's currency tbh.
