What is Handedness?
Handedness is a human attribute defined by unequal distribution of fine motor skills between the left and right hands. An individual who is more able with the right hand is called right-handed and one who is more skilled with the left is said to be left-handed. The majority of infants have developed hand preference by 6 months of age.[1] A minority of adult people are equally skilled with both hands, and are termed ambidextrous. It is one example of body laterality.

What Are the Origins of Handedness?
* Genetic component
* Seems to run in families
* Identical twins
* Frequently differ in handedness

When Does Handedness Emerge?
* Emerges and shows preference during infancy
* Becomes strongly established during early childhood
* Majority of people are right-handed

Are There Problems Connected With Being Left-handed?
* Connections have been made with
* Language problems
* Dyslexia and stuttering
* Health problems
* Migraine headaches and allergies
* Psychological problems
* Schizophrenia and depression
* Higher frequencies of left-handers have been made with
* Mathematical abilities
* Athletic abilities
* Artistic, musical and architectural


What Are Children’s Nutritional Needs and Their Eating Habits Like in Early Childhood?
* Nutritional Needs
* Need more overall calories than toddlers
* Slower growth rate – less calories per pound
* Patterns of Eating

* Minor illnesses
* Respiratory infections
* Colds, sore throat
* Gastrointestinal upsets
* Nausea, vomiting, diarrhea
* In developing countries, diarrheal illness is leading killer of children
* Major illnesses
* Immunizations, antibiotics reduced major illness in US * One-third of children in US under 18 years suffer from some type of chronic illness
* Globally 13 million children die each year

* Two-thirds die of pneumonia, diarrhea, measles, tetanus, whooping cough and TB


How Much Sleep is Needed During Early Childhood?
* Preschoolers average 10 to 11 hours per 24 hour period
* 9 to 10 hours at night
* 1 to 2 hour nap

* Insomnia
* Somnambulism (sleepwalking)
* Onset between ages 3 and 8
* Occurs early in night during deep sleep


When Are Children Considered To Be Gaining Control Over Elimination Too Slowly? * Maturation plays a critical role in toilet training
* Most US children are trained between 3 and 4
* Enuresis
* Based on age of child and frequency of “accident” * Bed-wetting
* More frequent in boys than girls
* Numerous causes
* Organic, psychological, stress, sleep disorder

What To Do About Bed-wetting?
* Encopresis
* More common in boys than girls
* Less common than enuresis, more common in daytime
* Causes may be physical or psychological
