Slowly getting better?? - WAW advice still needed.

I will also (in addition to mommy) be angry with him when he's bad at school.

But I also mean of course that I will be angry when he's bad

he will equate you being angry because he is bad

He's eager to make daddy happy with him

Daddy happy = me good

I know this isn't what you want to get across. His behavior will have healthy consequences good and bad. The way you are phrasing it gives a kid the impression he is responsible for your feelings. Don't tell him he is bad, tell when you do this then this will be the consequence. "If you get a detention at school then I will ground you this weekend." No one can make you angry. Just tweak your delivery.

This makes me cringe a little. I grew up with parents who spoke like this and worse.

I will read up on you and check back.

Cheers
