how can a mother hurt her child how can you get mad at a little baby and shake it ? or hit it in the face a BABY .. I don't understand how people could do this to their own child or any child I am seriously in tears it makes so fucking pissed off that someone could do that and still be alive .. the way people treat their kids these day is just heartless gutless pieces of shit.
