HPC 3O1 - Physical Development in the First Year

  1. 1. What can we expect from a baby in the first year?
  2. 2.  Monday – Physical Development Tuesday – Social/Emotional Development Wednesday – Intellectual Development Thursday – In-Class Assignment: Development Collage
  3. 3. Thomas Balmes’ documentary film “Babies”, 2010
  4. 4.  Not all babies develop at the same rate. Growth and development do not follow a timer, but are greatly affected by external factors! Development is non-linear. Patterns of physical, emotional/social and intellectual stages will overlap. “cross-influence” or interdependence.
  5. 5.  Growth: height, weight, proportion Sensory: sight, hearing, taste, touch, smell, and vocal abilities Motor Skills
  6. 6. Growth is the most rapid during the first year of life!! Week #1 Week #52
  7. 7.  Head to Foot  Growth begins with the head, and extends to the torso, and eventually shoulders, arms, and legs. Near to Far  Development starts at the trunk of the body and moves outwards (learning to roll over, then crawl, walk) Simple to Complex  Baby will transition from simple to complex tasks. Slowly, this allows the baby to fulfill their own needs.
  8. 8.  Slight weight loss immediately after birth Triple their weight in the first year! Gain = 1-2 lbs for the first 6 Months Average Weight = 20-22 lbs at 1 year Physical Activity, Eating Habits And Heredity. Weight Gain is a “good health”Indicator in newborns.
  9. 9.  Height is more “slow and steady” vs. Rapid weight gain Average at Birth = 51 cm 1 year = 76 cm Heredity has a greateraffect on height thanweight.
  10. 10.  Proportion - the size relationship of one thing to another. Proportionally: Large head and torso, and tiny limbs, vs. Adults with larger limbs Large head = rapid braindevelopment! ½ your total head growthoccurs before age 1.
  11. 11.  No light in the uterus = minimal vision development Uncoordinated muscles, “googly eyed” Eyes are often closed 14 days = Can see 7 to 10 inches away 2 Months = develop depth perception, “see in 3-D” 3.5 Months = Normal Vision! Eye-hand coordination
  12. 12.  Hearing begins to develop long before birth At birth babies can tell sound direction Respond to tone, not meaning Hearing difficulties = troublespeaking and listening Hearing tested by 6 Months
  13. 13.  Amniotic fluid prevents sense of smell At birth – responds most to unpleasant odours First few days – recognize familiar smells (Mom, Dad) Sense of taste develops quickly Differentiate between sweet,salty, sour and water soon afterbirth. Preference to sweet.
  14. 14.  Changes in throat, tongue, teeth and mouth allow new foods, noises, cries and sounds Over time allows for “distinctive cries” Vowel sounds come first, but teeth are needed for others Full words usually come after 1 year. Oral growth also allows for new foods/solids
  15. 15.  6-7 Months = primary teeth (first set) Teething - teeth forcing their way up through gums.  Painful, swelling, bleeding, drooling  Cranky, restless and wakeful  2-10 days per tooth, occurs over 2 years. What Helps?  Teething ring, ice, cold liquids, commercial meds, chewing.
  16. 16.  Motor Skills – Abilities that depend on the use and control of muscles. Very dependent on physical growth, but affected by social and intellectual as well. Head to Foot  1 Month – lifting head  3 Months – lifting chest  4 Months – sit with head steady, rolling over  5 -7 Months – reaching, pulls self up, “squirming”  8-10 – crawling, walks when lead, picking up objects  Page 235-236
  17. 17.  Name that development! Be Specific and use vocabulary from today!
