I know, this one may sound crazy. But when my brother was a little kid, he got bounced on and had his nose broken in a bouncy house at a carnival. Then this year, there were not one but two instances of kids getting carried away in them. That's enough to freak out this mom.
Likelihood That It'll Last (on a Scale of 1-10): 2 — While I can probably avoid having one of these in my own backyard, it's only a matter of time before we encounter a bouncy house at a carnival, block party, or birthday party. And if I know myself, I know that I'll give in.
