Final answer:
Toddlers, defined as children aged 1 to 3 years, experience rapid physical and cognitive development as they learn to walk and manage other motor skills. Growth rates in this stage slow down compared to infancy, and activities like walking provide significant developmental benefits. By three, children gain proficiency in climbing stairs, handling objects, and beginning to form simple sentences.
Step-by-step explanation:
Toddlers, children aged between 1 to 3 years, undergo significant physical development which includes learning to walk or toddle. As toddlers gain more control over their movements, they learn to walk sideways, backward, and can even run, though they are prone to falling. By the age of two, they can walk up and down stairs holding onto a rail, build towers with blocks, and are beginning to master self-feeding and potentially toilet training. By three years, gross motor skills are developed enough for climbing stairs without assistance, and they have advanced fine motor skills for handling small objects and doing simple puzzles.
The process of learning to walk is quite involved, requiring the coordination of multiple brain regions and muscle groups. Toddlers typically take about 2,200 steps and travel around 650 meters, and can fall up to 15 times per hour while they perfect their walking skills. Their brain cells benefit from such exercises, and growth continues at a slower pace compared to infancy, with roughly 52 percent weight increase and about 26 percent height increase from age one to three. The preschool stage marks further enhancements in physical capabilities, cognitive development, and language skills.
