How do children develop gross motor skills? Researchers frequently use what is called a “dynamic systems approach” to describe these evolving abilities in children—and adults. In simple words, this means that your children's development is influenced by physical capabilities, environment and the demands of the activity in which the are engaging. An example of this is a young toddler trying to walk across a room with toys scattered on the floor. While she knows how to walk, the environment makes it a bit more difficult and frustrating for her to reach the other side without tripping or swerving. So, she might decide that crawling is a better bet—and reaches the other side successfully. As she gets older and taller and her stride lengthens and balance improves, she will be able to easily walk across that floor, obstacles and all!
