Child development stages are the theoretical milestones of child development, some of which are asserted in nativist theories. This article discusses the most widely accepted developmental stages. There exists a wide variation in terms of what is considered "normal," caused by variation in genetic, cognitive, physical, family, cultural, nutritional, educational, and environmental factors. Many children reach some or most of these milestones at different times from the norm.

Holistic development sees the child in the round, as a whole person - physically, emotionally, intellectually, socially, morally, culturally and spiritually. Learning about child development involves studying patterns of growth and development, from which guidelines for 'normal' development are drawn up. Developmental norms are sometimes called milestones - they define the recognised pattern of development that children are expected to follow. Each child develops in a unique way; however, using norms helps in understanding these general patterns of development while recognising the wide variation between individuals. This page talks mostly about the linguistic development of a child.

One way to identify pervasive developmental disorders is if infants fail to meet the development milestones in time or at all.

Milestones by age

1-4 months

Physical

Head and chest circumference are nearly equal to the part of the abdomen.
Head circumference increases approximately 2 cm per month until two months, then increases 1.5 cm per month until four months.
Increases are an important indication of continued brain growth.
Continues to breathe using abdominal muscles.
Posterior fontanelle.
Anterior fontanelle.
Skin remains sensitive and easily irritated.
Legs may appear slightly bowed.
Cries with tears.
Gums are red.
Eyes begin moving together in unison (binocular vision).
Responds to and thrives on warm, sensitive physical contact and care.
Expresses discomfort, hunger or thirst.
Has very poor vision. The infant has trouble focusing on objects and could barely make out images with its eyes.

Motor development

Rooting and sucking reflexes are well developed.
Swallowing reflex and tongue movements are immature; inability to move food to the back of the mouth.
Grasp reflex.
Landau reflex appears near the middle of this period; when baby is held in a prone (face down) position, the head is held upright and legs are fully extended.
Grasps with entire hand; strength insufficient to hold items. Holds hands in an open or semi-open position.
Movements are large and jerky.
Raises head and upper body on arms when in a prone position.
Females have more arm synchronous coupling.
Males have more leg synchronous coupling.
Turns head side to side when in a supine (face up) position; cannot hold head up and line with the body.
Upper body parts are more active: clasps hands above face, waves arms about, reaches for objects.
According to Sigmund Freud, the infant is in the oral fixation stage. The oral fixation stage is when the infant begins to root and suck.

4-8 months

Physical

Head and chest circumferences are basically equal.
Head circumference increases approximately 1 cm per month until six to seven months, then 0.5 cm per month; head circumference should continue to increase steadily, indicating healthy, ongoing brain growth.
Posterior fontanelle closing or fully closed.
Anterior fontanelle.
Breathing is abdominal; respiration rate depending on activity; rate and patterns vary from infant to infant.

Also they are very active

Teeth may begin to appear, with upper and lower incisors coming in first. Gums may become red and swollen, accompanied by increased drooling, chewing, biting, and mouthing of objects.
Legs may appear bowed; bowing gradually disappears as infant grows older.
Fat rolls ("Baby Fat") appear on thighs, upper arms, and neck.
True eye colour is established.

Motor development

Reflexive behaviors are changing:
Blinking reflex is well established
Sucking reflex becomes voluntary
Moro reflex disappears
When lowered suddenly, infant throws out arms as a protective measure.
Swallowing reflex appears and allows infant to move solid foods from front of mouth to the back for swallowing.
Picks up objects using finger and thumb (pincer grip).
Reaches for objects with both arms simultaneously; later reaches with one hand or the other.
Transfers objects from one hand to the other; grasps object using entire hand (palmar grasp).
Handles, shakes, and pounds objects; puts everything in mouth.
Able to hold bottle.
Sits alone without support, holding head erect, back straightened, and arms propped forward for support
Pulls self into a crawling position by raising up on arms and drawing knees up beneath the body; rocks back and forth, but generally does not move forward.
Lifts head when placed on back.
Can roll over from back or stomach position.
May accidentally begin scooting backwards when placed on stomach; soon will begin to crawl forward.
Looks for fallen objects by 7 months
Plays 'peek-a-boo' games
Cannot understand "no" or "danger"

8-18 months

Physical

Respiration rates vary with activity
Environmental conditions, weather, activity, and clothing still affect variations in body temperature.
Head and chest circumference remain equal.
Anterior fontanelle begins to close.
Continues to use abdominal muscles for breathing.
More teeth appear, often in the order of two lower incisors then two upper incisors followed by four more incisors and two lower molars but some babies may still be waiting for their first.
Arm and hands are more developed than feet and legs (cephalocaudal development); hands appear large in proportion to other body parts.
Legs may continue to appear bowed.
"Baby Fat" continues to appear on thighs, upper arms and neck.
Feet appear flat as arch has not yet fully developed.
Both eyes work in unison (true binocular coordination).
Can see distant objects (4 to 6 m or 13 to 20 ft away) and points at them.

Motor development

Reaches with one hand leading to grasp an offered object or toy.
Adjustment from grip emerges around 8 months.
Manipulates objects, transferring them from one hand to the other.
Explores new objects by poking with one finger.
They adjust their grip based on touch at 8 months, not yet visual cues.
Infants will begin to use visual cues while reaching and grasping after 9 months of age.
Uses deliberate pincer grasp to pick up small objects, toys, and finger foods.
Stacks objects; also places objects inside one another.

Beginning to pull self to a standing position.
Beginning to stand alone, leaning on furniture for support; moves around obstacles by side-stepping.
Has good balance when sitting; can shift positions without falling.
Creeps on hands and knees; crawls up and down stairs.
The hip and knee joints exhibit a greater lag than the shoulder and elbow joints, which shows that motor skills develop in a cephalocaudal trend.
The lags between joints decreases as age increases.
The hip and knee joints are more strongly coupled than the shoulder and elbow joints in interlimb comparisons. This may be due to the weight bearing the hip and knee joints go through for standing and walking.
Walks with adult support, holding onto adult's hand; may begin to walk alone.
Watches people, objects, and activities in the immediate environment.
Responds to hearing tests (voice localization); however, loses interest quickly and, therefore, may be difficult to test formally.

Motor planning includes an individual's choice of movements and trajectory of such movements. Children begin to display motor planning in preference of certain body parts such as hand preference.

The preferred hand selection of children would also be displayed in other motor tasks.
Children show significant increase in sensitivity to end-state comfort
End-State Comfort is the preference to initially use unusual uncomfortable postures and movements to end in a comfortable position. One common method of studying end-state comfort is the task of over-turned glass. In this task, individuals are asked to use one hand to pick up a drinking glass that is placed up-side down, turn it upright, and pour water from a given cup into the glass. Once the children begins to grab the upside-down glass with thumb pointing down, then they have displayed end-state comfort. As a result, once they have turned over thr glass, the child would have ended with palm holding the glass in a comfortable position.
