True or False: Most infants have learned many of the basic motor skills by the time they are a year and a half old.

By the time infants reach the age of 18 months, they typically have developed many fundamental motor skills that allow them to engage more actively with their environment. At this age, most children can walk independently, which marks a significant milestone in gross motor development. They often have gained skills such as standing, climbing, and possibly even running or kicking a ball.

Fine motor skills also show considerable development by this age, as many infants can grasp small objects, use a pincer grip to pick up food, and may even be able to stack a few blocks or turn the pages of a board book. This accumulation of skills is a natural progression during the first year and a half of life, demonstrating how infants rapidly refine their motor abilities as they grow.

While some variation exists in the development timelines of individual infants, the general expectation is that, by 18 months, most will have achieved many basic motor skills, supporting the assertion that the statement is true.
