How to Mix Soy & Milk-Based Formula

Switching formulas for your baby is best done by gradually transitioning from one type of formula to another. You can help your baby's body make a smoother transition by mixing different kinds of formula for a couple of days until the baby's body gets used to the new formula. Mixing soy and milk-based formulas is common if you are switching from one formula to another. Allergies typically are the reason for a formula switch. Milk allergies are one reason to switch an infant from a milk-based to a soy-based formula.
