Physical development. Typically grows at a similar rate to the previous month, usually growing between 1 and 1.5 inches (2.5 and 3.8 cm) and gaining about 2 pounds (910 g). [23] Resting heart rate is usually between 80 and 160 beats per minute, and it typically stays within that range until the infant is about one year old. [18] Motor development
Early childhood development is the period of rapid physical, psychological and social growth and change that begins before birth and extends into early childhood. [1] While early childhood is not well defined, one source asserts that the early years begin in utero and last until 3 years of age.
The speed of physical growth is rapid in the months after birth, then slows, so birth weight is doubled in the first four months, tripled by 1 year, but not quadrupled until 2 years. [85] Growth then proceeds at a slow rate until a period of rapid growth occurs shortly before puberty (between about 9 and 15 years of age). [86]
Newmeyer suggests parents download the CDC's free milestone tracker app, which can help parents keep tabs on their child's development from ages 2 months through 5 years old.
Development before birth, or prenatal development (from Latin natalis 'relating to birth') is the process in which a zygote, and later an embryo, and then a fetus develops during gestation. Prenatal development starts with fertilization and the formation of the zygote , the first stage in embryonic development which continues in fetal ...
In psychology, the term early childhood is usually defined as the time period from birth until the age of five or six years, [1] therefore covering infancy, Pre-K, kindergarten and first grade. There are three simultaneous development stages: [ 2 ] It is distinct from early childhood education , and does not necessarily refer to the same ...
A toddler is a child approximately 1 to 3 years old, though definitions vary. [1] [2] [3] The toddler years are a time of great cognitive, emotional and social development. The word is derived from "to toddle", which means to walk unsteadily, like a child of this age. [4]
Jean Piaget's cognitive developmental theory describes four major stages from birth through puberty, the last of which starts at 12 years and has no terminating age: [11] Sensorimotor: (birth to 2 years), Preoperations: (2 to 7 years), Concrete operations: (7 to 11 years), and Formal Operations: (from 12 years). Each stage has at least two ...
