What is a common characteristic of children achieving gross motor milestones?

Children who achieve gross motor milestones typically demonstrate increased physical activity levels, including actions like running, jumping, and climbing. These milestones are crucial as they reflect the development of large muscle groups and overall coordination. As children grow and develop, engaging in physical activities not only helps them meet these milestones but also enhances their strength, balance, and overall motor skills.

In contrast, remaining stationary, focusing on academic skills, and avoiding group play do not align with the characteristics of children mastering gross motor skills. Children reaching these milestones are usually more active and exploratory, which fosters social interaction and physical engagement within their environments. Thus, the correct answer highlights the energetic and active nature of children developing their gross motor capabilities.
