Patterns of Development

Patterns of physical development Head to Foot Babies develop control of head and neck muscles first, then control of muscles move down baby and end with control of legs and feet Head and neck then Legs and feet

Patterns of physical development Near to Far Development begins at the trunk of the body and moves outward to hands and feet Trunk/body Hands and feet Trunk grows first then leaves….body develops first then hands and feet

Patterns of physical development Simple to Complex Large muscle development takes place first leading to more fine muscle and complex abilities later Large then small muscles

Growth

Physical Facts about Infants Vision Length Blurry at birth 20 inches long

Weight (Wt.) Infant gains 1-2 lbs per month in the first six months Wt. gain is one of the best signs of good health Growth is related to good eating habits and excerise Most babies lose about 10% of their birth wt. in the 1st 5 days of life Afterward, they gain wt. rapidly Gain 1-2 pounds (lbs) per month in the 1st 6 months Gain 1 lb per month in the next 6 months Average wt. of a 1 yr. old is 20-22 lbs.

Length Measure lying down Measure length instead of height because they are lying down Average baby is 20 inches long at birth Boys are slightly longer than girls Average baby at 1 yr. is 30 inches long

Body shape: Infants hold themselves in a tightly secured position with fists clenched Skinny arms and legs, large abdomen Navel cord usually falls off in 3 wks. Body straightens out during the 1st 6 mths.

Proportion Size relationship between different parts of the body Baby’s head and abdomen are large, and the legs and arms are short and small

Fontanels Open space in babies skull Allows for brain growth Usually close up by age 2

Infants and their 5 Senses

A stimulating environment Draw symbols to represent each of the five senses as you take notes. Baby has a wide variety of things to: See Taste Smell Hear Touch

Vision - Seeing Improves rapidly during the 1st yr. Blurry at birth within week or so, infant is aware of surroundings By 1 mth. infant can focus on objects as faraway as 3 feet an infant can not focus on objects across a room By 6 mths. eyesight reaches the sharpness of adult vision Child sees two-dimensionally (see object flat) 1st and then develops depth perception (three-dimensional) Distance awareness

Vision Two-dimensional Three-dimensional seeing an object flat see all sides of an object

Hearing Develops before birth Can tell the direction of sound Language develops with hearing spoken words

Touch Babies rely on touch of others to teach them about the environment For exploration (discovery) Becomes a more important sense for learning as year progresses They will pick up and explore different things such as toys

Smell & Taste Develop after birth Within 10 days they can distinguish their mother from any other person by smell Two-week old babies can taste the difference between water, sour, sugar, and salt, and milk

Voice Their voice is shrill (sharp, harsh), but softens as lungs mature Change in the voice results from physical growth of the throat muscles Tongue Lips Teeth Vocal Cords Change in tongue and in the shape and proportion of the inside of the mouth during the first months of life leads to speech development

Motor Skills

Motor Skills At birth babies have little control over their muscles Gross motor skills develop 1st Large muscles Arms Legs Fine motor skills Small muscles Hands Fingers
