Make sure you take some time with just him. I had have found when mine start acting up like that, they usually just need some 1 in 1 time.
Plan a dad/son day with some new experiences sprinkled with things he likes to do.
Good luck, you’re doing great!!!
Some part of his hobby or something he can do by himself. It’s easy to put the kids at the forefront of everything, but we need some time / hobby for ourselves.
