Once your baby can sit up without any help, it won't be long until he's mobile. And once he's moving and shaking on all fours, he'll be off to discover places unknown. Doors are a big attraction for babies since they can open and close them all by themselves! But the downside to this door fascination is that little fingers often wind up getting hurt by a door that slams shut. You'll want to be sure to protect your infant's sweet little fingers, hands, and feet from being harmed by a closing door with a foam finger guard. They're a cinch to install: The foam cut-out grips to the side or top of just about any door frame. Once the door needs to be shut, simply pop off the guard. The Kidco Finger guards come in packs of two.
