The Gro-egg (from L Mitchell L Mitchell Roden Company) changes color to let you know whether the temp of a room is too low/high/just right. Muse Sumner how neat is that! plus its a neat little night light.
It doesn't get much more luxurious than Stokke's XPLORY Winter Kit. The kit includes an insulated hood with a removable sheepskin rim, a storm cover to block the wind, and sheepskin-lined handmuffs to keep parents' hands toasty while out for a stroll.
