This document summarizes key physical, developmental, behavioral, and health milestones for toddlers between ages 2-3 years. Physically, toddlers continue to grow in height, weight, and body proportions. Their facial features and teeth develop and bones increase in density. Motor skills improve as they learn to walk, run, jump and use their hands for activities like drawing and puzzles. Toilet training progresses during this time. Cognitively, toddlers' thinking remains egocentric and they learn through play, imitation and trial-and-error. Socially, independence increases but parental guidance is still needed to help them learn right from wrong. Nutrition, sleep, safety and regular health checkups are also important
