The Stair Shield keeps toddlers from climbing up the OUTSIDE ledge and outside railings on staircases! Normal baby gates & stair gates only shield the top/bottom of stairs. But Stair Shield does what baby gates can’t do. It’s a brilliant solution to a very dangerous & common problem & can be used on stairs w/ gates or on it's own. It improves child safety & staircase safety so much that it should be a "must-have" baby product for anyone w/ toddlers who live in a home w/ a staircase!
