Childhood is the age span ranging from birth to adolescence. According to Piaget's theory of cognitive development, childhood consists of two stages: preoperational stage and concrete operational stage. In developmental psychology, childhood is divided up into the developmental stages of toddlerhood (learning to walk), early childhood (play age), middle childhood (school age), and adolescence (puberty through post-puberty). Various childhood factors could affect a person's attitude formation.
Early childhood is a stage in human development. It generally includes toddlerhood and some time afterwards. Play age is an unspecific designation approximately within the scope of early childhood. Some age-related development periods and examples of defined intervals are: newborn (ages 0–5 weeks); infant (ages 5 weeks – 1 year); toddler (ages 1–3 years); preschooler (ages 3–5 years); school-aged child (ages 6–11); adolescent (ages 12–17).
They are idols of hearts and of households; They are angels of God in disguise; His sunlight still sleeps in their tresses, His glory still gleams in their eyes; Those truants from home and from Heaven They have made me more manly and mild; And I know now how Jesus could liken The kingdom of God to a child.
Lord, give to men who are old and rougher The things that little children suffer, And let keep bright and undefiled The young years of the little child.
