My 15 yr old son and his 16yr old girlfriend just had a baby in Dec. He lives with his girlfriend and her mother and its not my choice. His dad said that he could, his dad has fully custody of him. But my problem is that the girlfriends mother wont let me keep my grandchild at all. I have tried to talk to her and she said that the only way is if my son and his girlfriend spent the weekend..Well now its a different story she is saying that she didnt say that. So I don't know what to do.
