Great suggestions on safety glasses and ear protection. Ear plugs won't work for young children. But some kind of ear protection is definitely needed, or the kids will grow up like me, and walk around saying "What?", "didn't hear you" a whole lot of the time.
Not hearing as well does have it's advantages though, as even when you do hear, you can pretend you don't and ignore what you didn't want to hear in the first place...
