Busting A Bad Mom? Discipline Or Abuse?

Vicki accuses her daughter Shawna of abusing her granddaughter, after she says she found 15 bruises on her and witnessing Shawna tell her she is “worthless” and “stupid.” Shawna admits to having “smack[ed] the crap” out of her daughter and telling her she was the biggest mistake of her life, but claims it was discipline. Shawna’s husband, James, says he generally agrees with his wife’s discipline and says it’s their daughter who is out of control.
