Dr. Brown's HappyPaci
The bulb is the same shape as Dr. Brown's bottle nipple, so a bottle-fed baby takes it without the usual week of rejection. One piece of silicone, so there's no seam to trap milk.

This is the one-piece pacifier made entirely of medical grade silicone, so there is no seam for bacteria to hide in and it can go through a sterilizer or a boil without worry. It is built for newborns still working out their suckling reflex, and the round, symmetrical nipple is designed to sit gently in baby's mouth without pressing the tongue against the mouth.
