Pacifier?

Melissa • First Glow baby in December 2016, just found out I'm pregnant again and due in March 2019.

So I boiled some pacifiers and bottles today, but noticed the mam brand pacifier got water stuck in the nipple as it boiled. Does this mean it's broken and should be tossed? I always thought pacifiers didn't get liquid inside them? My first never used them so I'm in the dark!
