Are her "methods" particularly successful? I don't think so, but apparently neither does she, otherwise she would not have sought help. I don't think her children should be taken away from her, but I think she needs anger management and perhaps some parenting classes. It bodes well that she sought help voluntarily and recognizes her loss of emotional control... <grimace> even if it is on a nationally syndicated pseudo-medical professional's television show.
The child abuse charges seem unnecessary in light of the circumstances that brought the issue up to begin with (mother seeking help), but a social worker following up with the family's progress is in order.
I wish that family good health and love. The last thing those children need is for their mother to be publicly lynched, however misguided she is (and this coming from someone who was abused as a child). It's important that we don't allow her emotional overreactions to invoke ours.
