INFANT                                DEVELOPMENT


3 Patterns of physical development is head to foot, near to far, and simple to complex.

                                         LENGTH AND WEIGHT

Length:                                                          Weight

Average baby is 20 inches long,                        Most baby lose 10% of birth weight in                                                                                 first 5 days of life,

boys are longer than girls, &                              Gain 1 to 2 pounds in first 6 months,

Average baby at 1 years old                              Average weight of an 1yr old is 20-22lbs. is 30 inches long.

                               CARING FOR INFANTS

Support the head of newborns

Babies can hold up their head without support at 4 months.

                                 PATTERNS OF DEVELOPMENT

Teething    :  

         Their first teeth are called primary teeth.

         Teeth start coming in at 6 months.

Dressing     :

        Clothes need to be stretchy and comfortable.

        By 6 months enforce clothing with padding for knees.

        Use one extra set of clothing than what you have on.

Diapering     :

          To prevent diaper rash change baby often.

          Disposable diapers is cheaper and better for environment, and convenient

Sleeping     :

         To prevent sids lay children on their back side.

         Newborn sleeps 16 hours in a 24 hour time period


MILESTONES - shows interests at 1 month

FEARS - expresses sadness between 1 & 2 months


         -shows disgust at 5 months

        -shows joy between 5 and 6 months

        -show anger at 10 months


1 month:                 The baby starts to coo and babble

2-3 Months:           Begins to smile and show excitement between 2-3 months

4-6 Months:          The baby laughs, squeals, babbles and reaches out with hands and                                   arms to play

7-8 Months:          Baby will learn to imitate sounds

9-10 Months:        Baby will learn to say simple words, objects if a toy is taken away

11-12 Months:       Uses gestures and body language and likes to spend time looking in                               the mirror


                                           BRAIN DEVELOPMENT

-Brain Stem : controls involuntary activities

-Cerebrum: direct motor activities

-Cerebellum: controls muscular coordination, balance, and posture

-Pituitary Gland: releases hormones that control metabolism & sexual development

-Thalamus: controls the way emotions are expressed

-Spinal Cord: controls simple reflexes that do not involve the brain


-Nerve cells in the brain that controls body function

-The brain works by dendrites, cell body, myelin coating, axon, synapse, and neurotransmitters.


CRYING            communicate discomfort, hunger, anger or pain & to bring a response

COOING           cooing at 6-8Weeks, coo more when talked to, smiled at, and touch

BABBLING       begin at 4-5Months, vowels/constant sounds slowly added to form                                  symbols

- Reaching for or pointing


- Pushing Away


-Give positive feedback as infant attempt to communicate

-Speak clearly using simple words

-Avoid using baby talk

-Talk about activities and things around them


Brain stem, cerebrum, cerebellum, pituitary gland, spinal cord, thalamus, dendrite, cell body, axon, myelin, synapse, stimulation, piaget's theory, sensorimotor period, language development, non verbal, object permanence, and word association deals are vocabulary words dealing with piaget.

Sensorimotor stage : children learn about the world through their senses and body movement

Stage 1: Birth to 1 Month, practice inborn reflexes, only aware of themselves, do not                      understand themselves as a different person

Stage 2:  1 to 4 Months, Combine 2 reflexes, wave fists, bring fist to mouth

Stage 3: 4 to 8 Months, Respond to other stimuli, improve hand-eye coordination

Stage 4: 8 to 12 Months, Intention Behavior, Learn certain actions lead to certain results,               imitate others, follow objects with their eyes, love playing peek-a-boo, objects                 still exist even when its out of sight

Stage 5: 12 to 18 Months, try to place object in another object, can find hidden objects,                understand objects exist independently

Stage 6: 18 to 24 Months, experiment mentally as well as physically, think about what they going to do before they do it.
