They're cute, creative, and keep wee ones warm, but BabyLegs' ($12) best use is one I recently discovered. My littlest guy just turned nine months and is all over the place — crawling, cruising, and pushing his walker — so he's been dragging his limbs across our hardwood floors and continues to take the occasional tumble. As his chubby legs thin out, the caps of his knees have gotten a bit of a floor burn when he's wearing just a diaper or onesie. Rather than keep him in sweats (that tend to crawl up) for cushion, I've been slipping BabyLegs on him around the house. In addition to padding him as he goes, he loves staring at their funky designs.
