the increasing maturation of the brain, combined with opportunities to experience a widening world, contribute to what ?
to children’s emerging cognitive abilities
what do changes in the brain during early childhood enable children to do ?
plan their actions, attend to stimuli more effectively, and make considerable strides in language development
does the brain grow as rapidly during early childhood as in infancy
no, the brain does not grow as rapidly during early childhood as in infancy, it undergoes remarkable changes
what types of growth do the children’s brains experince

until late adolescence or emerging adulthood
what do young children with higher cognitive abilities show
increased myelination by 3 years of age

more adventuresome than when they were 4

what was higher motor proficiency in preschool linked to
engaging in a higher level of physical activity in adolescence
by the time they turn 3 what develops of the children
their fine motor skills

its improved substantially and is much more precise
by age five what happens to fine motor coordination
better command of the eye
what is affected by the child’s eating habits
- skeletal growth
- body shape
- susceptibility to disease
who influences young children’s eating behavior
by their caregivers behavior
how can a childs eating behavior improve with caregivers
- eat with children on a predictable schedule
- model eating healthy food
- make mealtimes pleasant occasions
- engage in certain feeding styles
what do experts recommend for a caregiver to give according to tending to children’s eating habits
a sensitive, responsive caregiver feeding style
caregiver is nurturant
why are forceful and restrictive caregiver behaviors not recommended
can lead to excessive weight gain
is being overweight becoming a serious health problem in early childhood?
yes
how much percentage of children’s meals exceed the recommendations for saturated and trans fat
45%
- raise cholesterol levels and increase the risk of heart disease
what is the vegetable 3 year olds were more likely to consume
French fries, and other friend potatoes
what does BMI categorize
obesity, overweight, and at risk for being overweight
what does BMI take into account
height and weight
what is the BMI percentile to be classified as obese
at or above the 97th percentile for children and adolescents
what is the BMI percentile to be classified as overweight
95th and 96th percentile
