- We grounded my daughter for over a year for getting C's. By grounded I mean never allowed out of her room except to pee and have quick showers. We expected all A's and B's. She cheated so we tacked on 6 more months. She also kept sneaking out and seeing friends and skipping church so we tacked on more time. My mother in law was furious she wasn't allowed to Attend Christmas dinner again so she sued us for custody and won. My daughter blames for giving her a eating disorder which she overcame and pstd. She also claims she became suicidal from being locked in her room so long.
