I'm a big proponent of homemade teethers like cold food, but natural remedies aren't practical when you're on the go. These Kammi Teething Dolls ($20) offer a simple solution to soothing baby's ailing gums. They look a bit like cotton gnomes, but the terrycloth dolls are crafted out of knots. You just dampen the knots, store the doll in the freezer for a while and then let baby bite away. The best part? The dolls can be machine washed.
