Some of the best ideas are born out of necessity. New mom Jacqueline Haberfeld should know: Wanting to tote her daughter around in a wearable infant carrier—but not wanting to add a bulky blanket to her load in cool weather—she invented the Popover. This cozy fleece suit has a hole in the back that allows it to fit over the baby and the straps of a Baby Björn or car seat (it also has a detachable hood and cuffs that turn into mittens). Popovers come in pink, blue, black, green, khaki, and red. $90; 917-405-2536; www.popoverbaby.com.
