I'm new to the forums, what does rbbm mean? My brain can't figure it out.
Also, I personally feel it was a step further, especially since the parents were charged with aggravated child abuse. My thoughts at this time are that the parents were acting this way as a "punishment" or to "discipline" Ruby for some perceived slight. She cried and had trouble going to sleep, so they played music nonstop to drown her out (then said she couldn't sleep without it). She was somehow fussy at the table with the family, so they started feeding her in the crib alone. She 'escaped' the crib, so they put mesh to prevent her from getting out on her own.
