Set out a silicone mini muffin mold, or line a metal mini muffin tin with silicone liners. Silicone is highly recommended because it releases the frozen bites easily without any fuss.
Shake the can of coconut milk vigorously for 30 seconds. Coconut milk separates in the can, and you want it fully blended before opening.
In a medium bowl, whisk together the coconut milk, pear puree, maple syrup, vanilla, and cinnamon until completely smooth and uniform. No lumps.
Pour the mixture evenly into 12 mini muffin cavities, filling each about 3/4 full. A small ladle or measuring cup with a spout makes this easier.
Carefully transfer the mold to the freezer on a flat surface so the bites freeze evenly.
Freeze for at least 4 hours, or overnight, until completely solid all the way through.
To serve, gently push the bites out of the silicone mold from underneath. (If using a metal tin with liners, peel the liners away.) Let sit at room temperature for 1 to 2 minutes before giving to babies and young toddlers.
