Depends on if its what she wants?
== == 'Girlfriend', or depending on her standing with your son, your 'grandchild's mother'.
Your mother's mother is your grandmother. You are her grandchild.
You are his grandchild.
Model
A paternal grandmother with permanent custody of her grandchild is considered a family member rather than a parent. While she may have assumed the role of a parent by providing care and custody, her legal status is that of a grandparent.
Unless the grandparent is the legal guardian of the grandchild, or if the mother is still a juvenile, the grandparents have absolutely no responsibility to the grandchild.
Answer: We would call Her your "Great Grandmother" ~ 1)your Moma's Mother would be your Grandma or GrandMother. 2) your Grandmother's Mother is your Great-Grandma or Great-Grandmother .. {1) you are your Mother's Child. 2) You are your Grandmother's Grandchild , and you are the Great Grandchild of your Great Grandmother....
FOR MY OPINON NO BECAUSE GRANDMOTHER IS BLOOD AND ELDERLY AND HALF SISTER IS IN BY MARRIAGE SO YOU DON'T COME IN A FAMILY AND DISREPECT ELDERLY If the half-sister is the mother of the grandchild, or has legal custody of the grandchild through other means, she may have the authority to stop the grandmother fro seeing her grandchild, depending on whether the state in which the grandchild lives has laws establishing grandparents' rights.
You should be able to get your grandchild, because it is not good for the child to have no chance of finding friends and have a normal life, that is never something what a child should live, it is very important that you get your grandchild! Greets from Germany :)
Not unless they go to family court and have the mother declared incorrigible and deemed a ward of the state. Then they would need to request that they be granted temporary custody of the grandchild.
your great cousin twice removed.........i think
Your mother's sister is your aunt. Your aunt's child is your first cousins. Your aunt's grandchild is your first cousin, once removed. Your aunt's great grandchild is your first cousin, twice removed.
