Should get stock in Gerber

Abby has a pacifier preference: she'll only take the ones with the shield that cups away from her face or is flat. The ones from the hospital--big green rubber ones--are flat, and Gerber makes some that curve away. 'Course I have about five packs of regular ones that she refuses, and the five packs of the ones she likes have completely disappeared. How is it we can own ten pacifiers and I can only find one?? Are they hanging out with lost socks and pens? Or do they have their own black hole somewhere in the house? We tried to assign one or two to each room of the house where she hangs out, and left one in her diaper bag and one in her carseat, thinking that this would help us to hang onto them. But no. I'm not sure where the system broke down, but it most certainly did. Anyone have any suggestions for hanging onto them?
