Feeding volumes vary per baby.
We recommend that you first consult with your pediatrician.
We also recommend that you start with one box of your preferred formula before giving birth despite any prior experiences. It is entirely possible that one child can have an allergy that it's siblings did not have. Have the box ready to use and if the box works, proceed with a larger order of two boxes. Continue to purchase formula this way for at least a month before proceeding with a bulk order. Allergies can develop in later stages. Repeat this process when transitioning between stages or formulas.
