Might I suggest that she makes sure that the children grow up knowing what not to do around the dog. Like no encouraging of poking the face or fingers in the mouth. All the pits I've met have been wonderful with kids, when the owners are responsible and train the dog, like any other new dog in the family!

Might I sooth your worries with a story? My best friend's mother has a 3 year old child that has grown up with 1 pit bull and 1 pit lab mix. The dogs are ecstatic and friendly around us, but I have never seen a dog be more gentle around kids than they are. I would worry about my boxer mix toppling the young girl over, but they are so gentle with her, and put up with things like a kid-friendly dog does. I would not trust one of my cats around her (he nibbles a bit), but I fully trust them with her. Biggest loves I've seen, they coat me in kisses when I come in.
