Small bit of background since this is my very first post: I have 2 stepkids (ss8 & sd12) of whom my husband has 50% custody. Their mother is a nightmare who has a history of scaring away decent babysitters with her antics (general craziness, not paying them, etc).

I work from home and we recently hired a college student to pick the kids up from school and help with homework (I guess that's usually called a mother's helper). When BM found out, she demanded to know the girl's personal contact information and DH refused to give it to her.
