I really feel a bit at my wit's end. DS (10) has ADHD - every now and then (it's not constant) DH gets angry with him for 'careless' work or not 'making an effort' and lectures him about not being 'lazy' and that he should 'take pride in his work' and won't listen to me when I say it's not the way to go and what he needs is positive affirmation about what he's done right. Because it's going to massively undermining when DS has expended effort to get things right, but all he gets is an earful for what got wrong/didn't do - he'll just learn not to bother as his effort gets no recognition. And I've told DH this, I've told him that every childcare expert, psychiatrist, psychologist and ADHD expert says positive is the way to go but he still basically thinks I'm just being wet and wimpy and wanting to be nice for the sake of it. What I want, as I've told him, is to do what's effective - shouting feels like 'doing something', but all it achieves is harming his relationship with his son. Being positive is a long game and may not feel like you are getting anywhere but honestly, it's what works. It's come to the fore the last few days as I've been isolating for a hospital procedure so DH has had to be extra hands-on for several days.
It doesn't help DH comes from a shouty, lectur-y family, and also he has insecurities about achieving etc. Part of me is wondering if I can get him to just have a session with DS's psychiatrist, who DH does respect, to talk about learning strategies because then he might listen. Or I wish I could get him in a room with an adult with ADHD whose parents tried to shout it out of them so they could tell him how well that worked.
