Anna Lisa claims that her 18-month-old granddaughter has been traumatized by what she alleges is her daughter, Amanda, and Amanda’s fiancé, Alexis’s, “toxic” and abusive relationship.

“My daughter said it began when she would hide in the car and Alexis would attack the car, hit the car – bang the car,” says Anna Lisa, who has been caring for Amanda and Alexi’s children since Child Protective Services removed them from their parents.

“These allegations don’t make any sense,” says Alexis in the video above, adamantly denying that he or Amanda have done anything to traumatize their children.
