Answer:
"You just need to practice, and maybe you should work on your motor coordination."
Explanation:
The body's ability to develop movement is called motor coordination.
Skipping, running, walking, jumping, or performing tasks that require more skill, such as holding a pencil, embroidering, drawing, cutting, and juggling, all require motor coordination. For this reason, we can say that in the case of the girl who is trying to juggle and is failing, the best advice we can give her is that she needs to practice more and train her motor coordination.
Because the body is growing and can fix stuff faster, unlike adults where the body isn't growing as fast like children. At least that's what i think it is
