I think I’m a little out of the kid party know. Please help me out here...

My girl is turning one in May and we are having a smallish party at our house. Family and a handful of our closest friends. Well, our friends have a lot of kids. So it turns out there will be 15 kids between the ages of 1 and 7. (This includes inviting 4 neighbor kids because I don’t know how to throw a party and not include the neighbor kids.)

I was thinking of getting a face painter and a balloon twister. My sister thinks that is insufficient entertainment, and that the kids will be all over the place making a mess. So what kind of entertainment do you provide at just a low key house party? Is there such thing as a low key party when 15 kids are involved? A bounce house will be a hard sell to my husband since we have personally seen some gnarly head injuries happen in them. We live at the end of a cul de sac. What would you do? I’m strongly considering cancelling the party.
