Toddlers and preschoolers at the age 2 to 5 beginning to master many basic movements, but they're too young for most organized sports. Toddlers who participate in organized sports typically don't gain any long-term advantage in terms of future sports performance.
At this age, unstructured free play is usually best. Try: Running, Trumbling, Throwing, Catching, Swimming.
Around age 6 or 7, most kids have the physical and mental skills they need to start joining in organized sports. Shu says you can get your child moving as early as she shows interest, and start with easier activities that won’t be hard to master - playing catch, kicking a ball, swinging a bat, or going for an easy swim. As she gets better with hand-eye coordination and physical activity, then you can introduce the idea of a team sport. Consider organized activities such as: T- ball, Softball or Baseball, Soccer, Gymnastics, ,Tennis, Martial arts etc.
“You may want to try less-competitive team sports at first - for example, recreational level rather than travel ball -so novices don't get intimidated by more seasoned players,” says Shu.
