What is a common behavior indicative of a toddler's developing motor skills?

The behavior of throwing and catching a ball is a clear indicator of a toddler's developing motor skills. At this stage of development, toddlers are refining their gross motor abilities, which involve large muscle movements. These activities require coordination and control, key elements in physical development. As toddlers learn to throw and catch, they are enhancing their hand-eye coordination, balance, and overall physical agility.

In contrast, creating long sentences and reading simple books independently require advanced cognitive and language skills that typically develop later, beyond the toddler stage. Similarly, sitting quietly and observing does not signify active engagement in physical skill development; rather, it reflects a more passive approach to learning and engagement with the environment. Therefore, the act of throwing and catching a ball is representative of the active exploration phase typical of toddlers as they master new motor abilities.
