Growth: Increase in a measurable quantity

Development: Aquisition of skills and abilities

What can prevent a child from reaching a growth milestone?

• disease
• food intake
• diabetes (infant/mother)
• premature
• genetic disorder
• parental substance abuse
• pre/post partum

Centiles:

• An infants growth an be expressed as centiles (aka centile lines)
• This allows comparison to an "average" value.
• If an infant is on 3rd centile for height, this means that in every 100 children, 3% would be shorter and 97% would be taller.

Development follows an "ordered sequence" and is th eaquisition of skills and abilities.

Fine Motor: Smaller movement, more refined control, for instance picking up a pen.

Gross Motor: Large muscle movements usually required for mobility.

Principles of physical development:

• It is continuous and flowing
• it is sequential- goes in certain order (crawl-walk-run)
• Key aspects of sequential development: Loosing involuntary reflexes and replacing them with voluntary reflexes.
• Direction of development:
• - top to toe- gains control of head first and legs last
• - inner to outer- control core first then limbs
• most children awuire skills by a certain age these are known as MILESTONES,
