Prep the banana: Use 1 small ripe banana. For an extra cold smoothie, use a frozen banana or add a few ice cubes.
Add yogurt: Scoop in 1/2 cup of plain whole-milk yogurt. Greek yogurt makes it thicker; regular yogurt blends lighter.
Pour in milk: Add 1/4 to 1/2 cup milk to reach your preferred consistency.
Start with 1/4 cup and adjust.
Flavor it (optional): Add 1/4 teaspoon vanilla extract and a tiny pinch of cinnamon.
Boost it (optional): Add 1 tablespoon nut or seed butter, 1 tablespoon rolled oats, or 1 teaspoon chia or ground flax. Choose one or two; keep it simple.
Blend until smooth: Blend on high for 30–45 seconds, scraping the sides if needed. It should be silky with no chunks.
Taste and adjust: If it’s too thick, add more milk.
If your toddler prefers sweeter, add a small drizzle of maple syrup or honey (for kids over 1).
Serve: Pour into a toddler-friendly straw cup. For very young toddlers, aim for a thinner consistency to make sipping easy.
