(Note: This is not all inclusive of my cloth diapering must haves - I'll list those in a later post!)
Breastflow bottles - GREAT for switching from breast to bottle. They help avoid confusion because they are similar to the breast in that they have to suck harder to get through the double nipple and it is a wide nipple as well.
Sophie the Giraffe teether - I always thought people were crazy saying you had to have this (as it costs $25 regular price) but M genuinely loves hers! Its a soft, natural rubber that must feel great on their aching gums during teething. I must warn you though - if you have older children - this toy can get awful annoying if they get their hands on it because they can squeeze it a LOT harder than babies and that squeak can sure get loud! :)
