Prepare with care

The NHS and AAP advise that plant-based milks should not be given as a drink before 12 months, though small amounts may be used in cooking.
For infants 6-9 months, soy milk should only be used sparingly to mix into food or recipes, not as a main drink. Breast milk or infant formula remains the primary beverage. Use a small splash to moisten food or introduce flavor, choosing unsweetened and calcium-fortified varieties. Introduce soy gradually to monitor for potential allergic reactions.
