Infant Development

Physical Development

Size ~ An average newborn baby weighs about 7 pounds, and is about 20 inches long. At one year, they typically weigh 20-22 pounds, and are about 1 foot tall.

Milestones ~ Physical milestones include developing reflexes, grabbing at things, controlling eye movement, and eventually learning to crawl and walk.

Caring For a Baby ~ Physical care is not easy, but can be made easier.  Be sure to always support their head and neck until they learn to hold it themselves.  Change diapers often to prevent diaper rash. Be sure to always feed the baby when it is hungry.

Patterns of Development ~Simple to Complex, Head to Toe, Near to Far.

Social & Emotional Development

Milestones ~Plays peek-a-boo, develops attachments, show anxieties when separated form something or someone.

Emotional Fears ~  Babies often develop fears of separation, strangers, and new places.

Emotionally, a child learns to recognize and express feelings and establish a unique personality. Socially, a child learns to show self-expression and interact with others.  They develop predictable patterns of growth.  Affection and harmony is key is to healthy emotional and social development.  A child must develop healthy attachments and relationships in order to grow and build trust as well as a healthy self-concept.

Intellectual Development

Brain development ~ Infants prefer human interaction. This interaction helps their brains develop.

Neuron ~ Neurons are how a brain works.  Neurotransmitters are chemicals that pass information along through the neuron. Dendrites are where the information is passed. The myelin is what speeds up sending information.

Language ~Babies communicate through crying, cooing (6-8 weeks), babbling (4-5 months), and eventually have their first words (10-12 months).

Piaget ~ Piaget theorized 4 Cognitive stages.

  • Sensorimotor. Birth through ages 18-24 months
    --Learns through trial and error, develops object permanence, etc.
  • Preoperational. Toddlerhood (18-24 months) through early childhood (age 7)
    --Egocentrism, animism, can play with others, etc.
  • Concrete operational. Ages 7 to 12
    --Can use logic and reasoning, less egocentric, better at conversation, understands conservation.
  • Formal operational. Adolescence through adulthood
    --Able to classify objects more specifically using more logic, can think with more complexity/think abstractly.
