From birth to eight years old, it is a time of tremendous growth. Between birth and age three a child ordinarily doubles in height and quadruples in weight.

Around this age a typical three year old will have mastered walking, sitting, scribbling, toilet-training, using a utensil, and sufficient eye-coordination despite rapid growth.
Between ages five and three children will have developed fine-motor skills.
Physical growth typically slows down between five and eight years old, whilst body proportions and motor skills are becoming more sufficient.
Children also develop a spoken vocabulary that ranges between 300 and 1,000 words within the first three years of life.
