I am in a relationship with a 2yr old son. My BF has a daughter from previous relationship who never spends her visitation time with us. She spends it only with his parents. BF's mother is manipulative but BF doesn't see this. I speak frequently with BF's daugher's mother and know every issue that has occured with visitation. grandmother spoils granddaughter so much she doesn't even want to come visit us. Grandmother will take things from granddaughters backpack that are school related without mother's knowledge, intentionally buys the same christmas gifts on years they have her christmas morning to give them to granddaughter first... etc. I have also heard her speak negatively about BF's ex in front of child (9 yrs old so she def understands). My concern is this... relationship is on the rocks and if ends I fear same situation will occur. Especially because BF would move back in with his parents thus all visitation would be there even though he never would care for my son.. his mother would do all of that. I live in PA is there anything that can be done legally to limit grandmothers time with my son, I know she will intentionally spoil and manipulate him to favor her as she has with granddaughter. I would never want my son to not see them at all but BF only spends few hrs per week with daughter and never actually cares for her. Can I prevent all of this happening with my son?
