Document Summary
Lecture 3 focuses on chapter 4 (motor development) Sequence of growth follows a cephalocaudal (head to tail/top down) and proximodistal (center to outwards) pattern. Motor action control follows this trend too (ex. general arm movements occur before fine motor of fingers) Can also be a sign of neglect or trauma. First step is to identify cause, proceed with treatment accordingly. Brain development: is affected by maturation (nature) and sensory stimulation and motor activity (nurture). Instruction in genetic code on how maturation should unfold. Finishes around age 20 in cerebellum and frontal lobe. Human infants have more neural connections than adults. Nutrition: the canadian paediatric society recommends exclusive breastfeeding for the first 6 months of life. The foremilk is more watery while the hindmilk (later) is more fats and proteins. Reasons not to breastfeed: mother taking chemotherapy, mother is hiv-positive. Breast milk has more cholesterol + omega-3 fas, is easier to digest/absorb, contains immune boosters.
