Bear cubs are almost always warm, and have no need for hats. Your infant, though, has less natural insulation to protect him from the chill. A teddy bear toque keeps the heat in and provides a cheerful playmate. Even better, it can be made from a plain knit hat using nothing more than some cotton batting and a few quick stitches with contrasting yarn. Look for a tall hat with a rolled edge, like this one, or unfold the cuff of a ski hat. The end result proves it: Two heads are cuter than one.
