Attach a lightweight drone to your newborn infant, and interface it with a neural net implanted to its motor cortex. As it learns to crawl and then walk, it will simultaneously learn to fly. This will include learning its limits through a safe degree of trial and error when it’s small and limited to indoor spaces. Upgrade the drone to the necessary size and power as the child grows. Enjoy your awesome flying kid.
When the child is five years old, while it is sleeping, disconnect the system and never speak of it again.
