Physical and Cognitive Development
In
Early Childhood
(Three to Six Years)
DISCUSSION
Do children get enough exercise today?
Only one in three children are physically active every day. Less than 5% of adults participate in 30 minutes of physical activity each day;2 only one in three adults receive the recommended amount of physical activity each week. ... The national average for regular exercise is 51.6%. – HHS, 2017
Do you think there are any differences between the activity level of five and six year olds today versus fifty years ago? If so, why?

PHYSICAL DEVELOPMENT
PHYSICAL DEVELOPMENT SPECIFICS
Overall, the rate of growth slows
Height
Approximately two to three inches per year
At the start of this stage boys are slightly taller
By the end of the stage virtually no differences
Weight
Approximately four to six pounds per year
Increasingly the gain is due to muscle
Caloric needs decrease
Cholesterol can be an issue
APPEARANCE
Body Proportions
Lose their pot belly
Slim down
Body proportions “catching up” (more adult like)
MUSCULO-SKELETAL DEVELOPMENT
Ossification continues
Strength increasing (core)
Handedness starts (10% of pop. Left handed)
Art Development
Scribble Stage: Approximately age two
Shape Stage: Approximately age three
Pictorial Stage: Approximately age four / five
BODY SYSTEMS
Respiratory – Still developing
Circulatory – Still developing
Immune – Improving / Now independent
Nervous System (Brain)
By age six years = 90%
Synaptic pruning
Myelination
Expanding synaptic networks
Senses – All functioning
DENTAL DEVELOPMENT
Thumb sucking
Fluoridation
NUTRITION
Caloric needs decreasing
Problem of childhood obesity
“Picky eaters”
Vitamins
No link between sugar and A.D.H.D.
Current research suggests ADHD may be caused by interactions between genes and environmental or non-genetic factors. Like many other illnesses, a number of factors may contribute to ADHD such as:
Genes
Cigarette smoking, alcohol use, or drug use during pregnancy
Exposure to environmental toxins, such as high levels of lead, at a young age
Low birth weight
Brain injuries
NIMH
HEALTH
Sleep
Fluctuation of naps
Better sleepers now
Bed time routines
Transitional objects
Minor Illnesses
Immunizations
Seven to Eight per year
Major Illnesses
70% cure rate, pediatric cancer. NOT GOOD ENOUGH!

T/F – All of our senses are now fully developed.
A good parent is a “warm” parent.
T/F Weight gains increase during this span of life.
T/F During this stage, weight gains are all due to the increase of fat.
