Nothing’s worse than a dirty slide that doesn’t promptly send you to the bottom. You know the wax paper trick, right?
Take a couple of butt-sized sheets with you next time you go to the slide with your boy. Have him sit on one at the top, just make sure you’re at the bottom to catch him before he launches so he doesn’t do a faceplant.

Years ago I took my 6yo daughter to the park, and I brought some wax paper in my back pocket. Some older boys (8yrs or so) were already there, so I suggested they try it. They were skeptical but decided to give it a go. I told my daughter to pay attention.

Those kids were flying down the slide, landing rump first and laughing their sandy asses off.

I told my daughter to watch

So high and so long the slide way down is, I hope I survive. (tanks in the mind of a little guy)
