What gross motor milestone is observed at 24 months?

At 24 months, the ability to jump on two feet is a significant gross motor milestone. This skill showcases a toddler's improving balance, coordination, and strength as they engage in more complex movements. Jumping requires the child to develop not only the necessary muscle strength in their legs but also the ability to coordinate their limbs effectively. Mastering this skill indicates progress in physical development, as it reflects both confident movement and increased independence.

In contrast, pulling to stand, rolling over, and holding their head up when prone are milestones that typically occur at earlier developmental stages. Pulling to stand usually happens around 9 to 12 months, rolling over is commonly acquired around 4 to 6 months, and holding the head up when prone is generally expected by 2 to 4 months. These earlier milestones lay the foundation for the more advanced gross motor skills seen at 24 months, such as jumping. Therefore, jumping on two feet at 24 months marks a crucial advancement in a child's gross motor development.
