Fostering a Dog With a History of "Nipping" Children?

From what I know of this dog, he's young and needs proper socialization. So I think there's time to help retrain him not to feel possessive or whatnot around children. This dog is reportedly amazing with adults, a lover.

I have some skill training dogs. But I would not be willing to foster the dog if he doesn't have a chance to learn some new manners.

Besides, it's impossible to find a neighbourhood with no children. Really. I can't imagine a place around where we live without kids. It's impossible.

I would rather work with the dog to see what we can do. The family who has him right now doesn't have the time to do the work. I understand why they're worried, but I also think that this puppy (he's only 8-9 months) needs attention. Of course, I would never trust him around young kids, but I also don't trust ANY dog around young kids.
