I bottle-fed my first baby, so my mother bought me the Avent sterilizer and it came in very handy. Add only a small amount of water to the bottom tray and the steam sterilizes the bottles (it also works well for breast pump parts). Once I absent-mindedly put in a pacifier tether, though, and the metal clasp melted a bit of the insert rack. But I kept the sterilizer and it still works. What a great idea.
