If you choose not to breast feed, then your probably asking yourself, should I use glass or plastic bottles? Believe it or not your baby may let you know which one they prefer better. There are certain things to consider, plastic bottles are lighter but may contain Bisphenol a chemical which is sometimes found in plastic and they don't seem to last as long as the glass bottle does. All baby bottles now are supposed to be BPA free. When my Son was born I chose to use glass bottles, to me they seemed more sanitary to use at the time. Today there are so many bottle choices on the market. What's your favorite? Would you use glass or plastic?
