Your little crawler has no clue the knee bone’s connected to the thigh bone. But he knows exactly where it hurts when he scuffs his patellas on your hardwood floors.
Don’t knee-jerk. Invest in a pair of Silipads instead.
The cotton and silicone kneepads slip over legs to prevent the scrapes, scuffs, and bruises that come with exploring new ground. Toss them in the washer and dryer when they get dusty.
Color combos (like orange/pink, blue/green) are so cute you’ll want your tykes to stay floor level forever.
No bones about it.
Available at Peekabootique, 1306 Castro Street, at 24th Street (415-641-6192); online at silikids.com.
