Ready. Set. Food! is a guided system to make early allergen introduction safe, easy, and convenient. Each daily pre-measured packet mixes easily in a bottle or food. Just shake or stir until dissolved and feed one packet daily. Stage 1 and 2 Mix-Ins will mix into a bottle of breast milk or formula or into baby food. Stage 3 Mix-Ins can be mixed into baby food but cannot be used in a bottle; it is important for your baby to use Stage 2 Mix-Ins for at least 2 months or until they are consistently eating solid food.
