These have got to be the greatest invention! I don't know how many times I washed and sterilized my sons' paci's as they were always dropping them! And for most babies (and parents) pacifiers are lifesavers!! The Keep-it-Kleen Pacifier is the only pacifier with this special "stay clean" shield. When the pacifier is dropped, the shields automatically close to keep the nipple clean! No more dirty pacifiers! These are available in various designs like a ladybug, soccer ball and more!
