preterm
Birth weight
irth weight is 2,500 to 4,000 grams or five pounds, eight ounces to eight pounds, 13 ounces. Low birth weight is anywhere from 1501 to 2,500 grams. Very low birth weight is 1000 grams to 1500 grams and extremely low birth weight is an infant that weighs less than 1000 grams at time of birth. Now there are a number of
factors affecting birth weight: Such as ethnicity, the maternal age, maternal health, amount of maternal weight gain in pregnancy, birth order, gestational age, and genetics.
Apgar score[1]:
- The Apgar score consists of five components (heart rate, respiratory effort, muscle tone, reflex irritability, and color), each given a value from 0 to 2. Thus, total scores range from 0 to 10, with higher scores indicating a better physical condition. e. The Apgar score provides an accepted and convenient method for reporting the status of the newborn infant immediatelypgar is a quick test performed on a baby at 1 and 5 minutes after birth. after birth
- grimace
- appearance
- respiration
Various ages
- gestationsal
- chronological
- adjusted or corrected age- when they were born vs. when they were supposed to be- use this for milestone for the first two years of life
Primitive Reflexes
develop in utero
as nervous system develops, they begin to disappear/integrated
absensce of it or persistance of one could indicate a neurological issue

spontaneous stepping
landaou

parachute
tonic reflexes
- atnr
- tonic labyrinth
- symmetric tonic labyrinth
righting reactions
- labyrtinth
- optic righting
- neck righting
- vertical righting
- rotational righting
