Since we’ve added a trampoline (free from friends in our Polish community whose boys, now in high school and college, have no interest in it) to our entertainment possibilities, I’ve come to see the whole potentially injurious toy in a whole new way. Sure, there’s the possibility broken bones, I guess, snapped spines, but in truth, I don’t think there’s the kind of jumping going on down there that could lead to such tragedies. And the advantages are overwhelming at times. There is of course the simple fact that it’s an enclosed space that allows the adults to relax while the kids go crazy.

But what I’ve noticed most is the incredible improvement in both the kids’ balance and, to borrow an eduspeak term, their kinesthetic intelligence. When we first began the jumping and bouncing, the Boy fell quite frequently. All you had to do is jump somewhat near him and the jolt of the trampoline below him would be enough to send him tumbling — laughing often but frustrated just as often. Now, we hop all around him, and he seems simply to absorb it all with a bit of knee action. He’s gone from little timid hops to being able to bound across the whole trampoline with only four or so jumps.

The Girl seems to enjoy it the most, though. We’ve lately been taking the whole popcorn idea to an absurd — and dangerous, K insists — level. Basically I launch her: she sits near the middle, I take a giant leap and land right beside her, and Newton’s third takes care of the rest — she pops up three, four feet into the air and lands on her feet. And if I get the timing just right, I launch her again at that moment, sending her flying yet again, making her laugh even harder. Which gets me to laughing. Which amuses the Boy. Which is why I ultimately have come to love our trampoline.
