Luminescent pacifiers
Night-time luminescent pacifiers
With pacifiers during the night, one ends up panicking over a lost pacifier in the dark, while one's baby's cries rapidly increase in strength. Night-time pacifiers have a self-illuminating piece (knob or ring) that lights up in the dark as long as you expose the pacifier to light before putting the baby to bed. So you can always find the pacifier when it gets lost during the night.
