Gross motor skills start developing in infancy, and keep improving throughout childhood. Kids don’t all develop at the same pace, but there are milestones they usually reach at different ages.
For example, at age 3 or 4, kids are typically able to jump with two feet. By 7 or 8, they can typically ride a bike without training wheels and catch small balls. Kids continue to get more coordinated during their tweens and teens.
