The postnatal stages of development are the neonatal period, from birth to 1 month; infancy, from 1 month to age 1 year; childhood, from age 1 year until sexual maturation begins; adolescence, which begins with the onset of sexual maturation (puberty) between ages 10 and 15 years and ends when growth in body size is completed (around 18 years); and maturity, which includes the rest of the person's life. A final stage called senescence, or aging, overlaps with maturity.
