Legally Kidnapped

My 2yo is calling the Foster Mother "Mama" and My 13yo went off about that. She told them that that woman did not carry that child for 9 months, be induced into a long and hard labor and on & on.

The 9yo's RCM told her she was out of line that the child spent all day with that lady and did not know that she was not her mama! At this point I told her that child did know who her Mama was and that it was inapprpriate for the woman to allow the child to call her Mama. She should be told no, my name is Ms.*&^%($#*.
