My child did not come home from the hospital liking mam pacifiers but several months later I discovered the best kept pacifier secret...Mam Night Time Pacifiers!!! These are like other Mam pacifiers in shape and style and are made starting for two months and up. They are livesavers in the middle of the night when mom and baby both need there rest and you can't find that comforting other pacifier. Mam night time pacifiers center circle glows in the dark and makes for a quick find for mom or baby to easily put back in the baby's mouth and continue sleeping. Because of SIDS guidlines babys should not sleep with pacifier clips and so I found this the only easy solution to loosing a pacifier in the dark. If you find that over time your pacifer does not seem to be glowing as much as it did before all you need to do is the old "hold the glow part next to the light trick" and you will have a brightly glowing pacifier once again. I found the set I got for my daughter to withstand lots of use and lots of boiling to sterlize over the course of a year or so and it is still glowing strong!
