How to Mix Soy & Milk-Based Formula

Mixing milk and soy-based formula can help transition your baby into changing their 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.
