Another thing: On my way to work this morning* I got a call from the W asking my opinion if she should keep S9 home from school today. He has a slight fever and has been coughing for the past day or so. Odd because usually she'd just make that decision herself and call just to inform me.
Someone may be advising her to document the ways in which she is cooperating with you, being a good mother, etc. Or she may be doing it out of guilt over other behavior that's not so noble, hard to say.
