How do you connect the brain to the new body?

Imagine your brain is like a radio that sends messages to tell your body what to do, and now it has to learn how to talk to a new body.

Think of your brain as a kid who used to wear shoes that fit perfectly. Now, they got a new pair of shoes that feel different, maybe bigger or softer. At first, the kid might stumble because they're not used to walking in them yet. That’s like how your brain learns to work with a new body. It sends messages through nerves, which are like wires connecting your brain to your muscles and skin.

Every time you move, like running, jumping, or even smiling, your brain says, “Hey, arm! Move!” through these nerves. In a new body, those wires might be longer or shorter, so the messages take a little more time to get there. But with practice, just like learning how to walk in new shoes, your brain gets better at talking to its new home, your new body!
