The question

My one year old granddaughter was conceived when my son was 15 and mother 20, whom was the daughter of a very close friends of the family. The two were raised as “cousins”. I signed temporary guardianship papers in order for my son to finish out his school year, instead of transferring to a new school. 3 months later ends up saying she’s pregnant. I found out days before the child was born that this is in fact my grandchild. Finding out recently that her mother warned her not to buy drugs and party with a minor. My son is not aloud to be on the birth certificate so she doesn’t get in trouble. My granddaughter is used as a pawn by her mother saying when she can come and not. I hand off, with the mother everyday so my granddaughter will know her fathers family equally. Now, the mother is saying someone from “our” home has treated her inappropriately. I struggle every time she leaves with her mother, beings she IS the perpetrator.
