I don't know about it attacking the child, but is it ever worth the risk?
Aggression is aggression, and if it was that brutal with another dog that wasn't even near it, I certainly wouldn't want it near a curious little kid who is pulling on it's ears.
To each their own, I just personally wouldn't take that chance.
Animals are unpredictably enough as it is....when they are displaying that kind of behavior it's a big warning for me.
