Here's what will happen with all of this. The media will get ahold of it and interview the witch of a mother. The witch of a mother will get her fifteen minutes of fame and doctors from all over the area will offer their services to help for free. The child will become more exposed to embarassment than he already has.
Another question comes to mind. Where is dad? Is he not part of the home? If he's not, perhaps he should look into custoday. If he is part of the home, he's not much of a man for letting his wife do something like this to his son.
Again, DCFS should be on this already and my guess is since Sis went away, they already are.
