If he is able to control his behaviour at nursery and with dad it suggests that he is testing boundaries with mum. Maybe she is less clear with him what the expectations are and takes the route of least resistance..easy to do..I have done that! Lots of praise & reward for positve behaviour and ignore ( as much as possible) the bad. If u can't ignore ( safety!) the bad try not to talk or get angry.. just remove him / objects to another place. A bit like dog training!
What did you you think you would have by your current age that you don't?
