what I get from your posts: The weekends, you are with six kids plus one spoiled teeny kid, your wife. I understand you are angry. I would too. I would be sooo angry (not helpfull
My first thought was sort of clear agreements about: You look for the kids from ... to ..., I look for them from... - to... But I fear this would not work with mental ill w, and with kids and a new born baby there is no space for trials. ?
I think the big question is, what can you do to improve this difficult situation. Or in other words: How to change the qualified anger to action.
