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.
Growth: height, weight, proportion Sensory: sight, hearing, taste, touch, smell, and vocal abilities Motor Skills
Growth is the most rapid during the first year of life!! Week #1 Week #52
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.
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.
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.
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.
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
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
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.
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
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.
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
