Hannah had her first baby two months ago and already has a great hack for a pacifier holder!
Our pacifiers seem to be constantly running away from home, and it's even more difficult to find them with a screaming infant in my arms. The commercially-made pacifier clips are expensive, bulky, and don't seem to work that well.
I tied a piece of grossgrain ribbon (about 5" long) to a medium-sized binder clip and then to the pacifier. It easily clips to her clothes or any other object. It makes the pacifiers easier to find in the house and harder to lose when we're out and about.
I clip one to my bedside lampshade so I don't have to fumble for it at night. Others are clipped to her carseat, bassinet, and front carrier. For safety reasons, I use only the shortest piece of ribbon possible to prevent it from wrapping around any part of the baby and choosing ribbon wide enough (at least 1/4") to keep it from winding around little fingers.
I remember well the days of the interminable pacifier search. Thanks for this, Hannah.
Safety note: Pacifier clips should only be used when you've got an eye on the baby.
