You know, in hindsight and giving this more thought, I have to agree with Blu.
As sad as it is, probably the best decision to find her a new home
I would consider this to be dangerous beyond any behavioral training. I do not beleive this dog should be allowed around any children at all. I hate to say it, but if this were me, the dog would have already been gone. Blessings - Blu
It can be. My parents had a little dog when I was a baby that would not let my father near me. They had to rehome her. You might try doing some research on the Internet or consult a trainer/ behaviorist.
