i forgot where i got this tip from, but thought i'd share it here. you know those little ketchup packets you get from fast-food restaurants? they're not only good for your fries, but they make great ice packs for your little one's bumps and bruises. simply place the ketchup packets in your freezer (they don't get hard like ice and the packets won't burst) and then take them out when you need them. they're the perfect size for little hands!
