my step daughter's real mom see's her every second weekend and bad mouths us (her biological father and me, his fiance) to our child. She plays victim in terms of not having money to fetch her daughter or buy clothes etc and our 10 year old is therefore constantly trying to side with her mom after listening to her manipulative explanations of how her lack of effort is our fault. We don't bad her mom to her and just correct or explain when we do things the way we do and refrain from speaking on her mothers behalf, we don't bad mouth her mom either.I can see this pains her and her mom wont think about her actions and how it affects her child. what can i do as a step parent?
