Prep your banana: Use 1 small to medium ripe banana. If your toddler prefers a cold smoothie, use a frozen banana.
Add the base: Pour 1/2 cup milk and 1/4–1/3 cup plain Greek yogurt (or dairy-free yogurt) into the blender.
Boost with healthy fats: Add 1 teaspoon to 1 tablespoon nut or seed butter, depending on your child’s age and appetite.
Thicken and fortify: Add 1–2 tablespoons rolled oats.
This makes it more filling and smooth.
Optional add-ins: Toss in a small handful of spinach, 1 teaspoon ground flax or chia, a pinch of cinnamon, and a tiny splash of vanilla if you like.
Blend until silky: Start on low, then go high for 30–45 seconds. You want a smooth, sippable texture with no grainy bits.
Adjust: If it’s too thick, add a splash more milk. If it’s too thin, blend in a few more oats or a couple of ice cubes.
Serve right away: Pour into a small cup or straw cup.
For very young toddlers, serve in small portions to avoid waste.
