Physical changes
first-year
-grow 25-30cm
-triple body weight
Physical: the brain
2 year-olds have proportionately larger heads as they need to hold their nearly full-sized brain
synaptogenesis
(creation of synapses) - is followed by a period of synaptic pruning(the process by which extra neurons and synaptic connections are eliminated in order to increase the efficiency of neuronal transmissions.) to make the nervous system more efficient
-(think of pruning as a throwing all the bad prunes Husein left out on the counter to make space for the good ones…the more important ones)
neuroplasticity
the brain’s ability to reorganize neural pathways and connections
myelinization
myelin gradually covers individual axons and electrically insulates them from one another- improving conductivity
-the abillity to think and process (so infants can learn on things)
REFLEXES
(1)Adaptive
-sucking-helps newborns survive (if cant suck they cant eat)
-some adaptive reflexes persist throughout life
-sucking on bottle to sucking on thumb to sucking on stripper’s tits
(2)Primitive reflexes
🧠
-controlled by primitive parts of the brain
-disappear by about 6 months (think of wooly mammoth (6) since it is extinct
REFLEXES
(1)Rooting
👄🌱🏔
a soft touch on the cheek will cause an infant to turn toward the touch and open the mouth - disappears by about 3 months
-think of roots (touch venus fly trap and then it will open its mouth)
REFLEXES
(2)Babinski
🦶🏼😂
stroking the sole of the foot causes the infants toes to fan out and up - disappears by about 12 months (think of helsinki getting hit in the face by a dozen of eggs)
-think of helsinki when he was a baby nirobi would tickle his feet and his toes fan out and up and he would laugh
REFLEXES
(5)Moro📢,🧨🏗⭐️
sudden noise or loss of support causes the infant to arch the back and throw the arms and legs out and then bring them back in
- disappears after 4-5 months (there are 4 words in moro and 5 points on a star)
Why the Moro reflex?👶🏼🛎👧⛑
It is hypothesized that it is to help the baby cling to the mother (safety reflex)
Behavioural States
😳
-neonates 80
-8 through night
-6 14
-consciousness:patterns of sleep/wakefulness STABILIZE with age
- neonates(0-28 days) sleep 80% of the time
-by 8 weeks, babies will begin to sleep through the night
-by 6 months, babies are sleeping about 14 hours a day
CRIES
basic cry=h
angry cry=l,i
pain cry= v a o
-mountain
CRIES
basic cry= hunger (I’m basically hungry -rhythmic)
anger cry=louder and more intense
pain cry= very abrupt onset
prompt attention to crying in the first 3 months leads to less crying later ( also think of 3 since there are three cries bap
