Prep the fruit: Wash the apple and pear well. Core them and keep the peel on for extra fiber.
Slice into chunks.
Soften the prunes (optional): If they’re very firm, soak in warm water for 5–10 minutes. Drain before blending.
Add to blender: Apple, pear, prunes, banana, yogurt, water (start with 1/2 cup), ground flaxseed, and olive oil if using. Add a pinch of cinnamon.
Blend until very smooth: About 45–60 seconds.
Add more water a little at a time until it’s easy to sip through a straw or drink from a cup.
Taste and adjust: If it’s too thick, thin with water. If your toddler prefers it colder, add a few ice cubes and blend again.
Serve right away: Offer 1/2 to 3/4 cup to start. Keep portions small and watch how your child responds.
