Circadian pattern of sleep 5 6th week wakefulness during the day Where your baby is going to sleep o baby in bed with you bonding cosleeping dangerous SIDS we can t explain why baby dies many asphyxiate while in bed with parents leading cause of death from infants in the first year crib in parents bedroom may lead to cosleeping start moving crib gradually Goal is to have baby in his her own room CHAPTER 5 NEWBORN S DEVELOPMENT OF PERCEPTION Physical Growth First Two Years Height and Weight changes o Newborn 7 5 lbs and 20 inches o 5 mo 15 lbs o 12 mo 22 lbs and 30 inches o 24 mo 26 lbs and 36 inches o grow in spurts rather than even progression Change in body proportions o cephalocaudal principle growth of head and upper body precedes the growth of the lower body head is 50 8th week after conception 25 at birth and 12 as an adult Breastfeeding o proximodistal principle grow from the center outwards reverse at puberty hands and feet grow and mature to size before other parts of body some boobs make more milk o proteins fats everything your baby needs o o 10 will not be able to produce enough and high quality milk to sustain baby o o o pediatrician will weigh baby and if not gaining enough you are not supplying size does not correlate with the quality and quantity of milk for baby you can breastfeed with fake boobs enough o nipple probz irritation pain not all nipples are the same infection of nipple because of breastfeeding nastitis advantages colostrum contains antibodies that can protect the baby before immune system is developed 50 less likely to develop fewer infections the first year 50 less likely to be obese by age 9 30 less likely to later have Type 1 Diabetes less likely to have ADHD in adolescence substantially lower rate of SIDS sudden infant death syndrome 36 lower rate of breast vaginal cancer in mothers lost baby weight more quickly American Academy of Pediatrics Mothers should breastfeed exclusively for the first 6 months pump that ish so dad or daycare can give breast milk buy expensive ass condoms baby mattresses and breast pumps Bottlefeeding o o no formula can reproduce what breast milk supplies cow s milk take proteins out cow only supplement Brain 40 years of research 100 billion neurons Average IQ 100 o This room 120 Smartest at conception all about potential whittles away when genes are turned off on requires high quantity and quality of stimulation highest potential met o wiring and structure is highest potential when a baby o o people may be born with potential to acquire a certain talent In the past people thought that some were genetically born smarter than others now people Krantz especially think babies are born with the same amount of potential at a genius level o Malnutrition teratogens and under stimulation decrease the potential over time o Age decreases the potential because the brain gets less stimulated structured challenged potential is not realized Human Perception sensation passive experience reaction of stimulation o passively receive and register information concerning internal and external events and to transmit that information to the CNS perception active explorative use reaction seeks stimulation o brain evolved that requires stimulation to grow need to search and is active o ex babies get better and better at search for and study objects what its brain needs o o actively use hands eyes ears better during development Visual Preference method researcher Robert Frantz presents pairs of stimuli to the baby researcher observes the infant between the two stimuli detects which stimulus the infant is looking at by the reflection of the fixated stimulus on the pupil of the infant s eye and record the changes in fixation o Result 2 day old infants discriminate among visual stimuli and preferred patterned stimuli such as faces and concentric circles to disorganized arrays of lines activity in the brain EEG measurement and interpretation of electrical Electroencephalography o Variations in brain wave patterns of different stimuli are interpreted as indications that the infant has perceived the stimuli as different o Research results show that verbal stimulation of infants directly modulates brain Habituation dishabituation procedure researchers take advantage of the fact that activity during perceptual task infants react to changes in sound smell taste or visual dispay by staring blinking ducking reaching or blushing and or by changes in heart rate and respiration As a particular stimulus is repeated at the same intensity infants habituate to the stimulus the intensity of their responses steadily decrease When the response is lowered by about half the original level the researcher makes a slight change and record the response If the infant does not have a change in response the researcher marks that the infant did not perceive the change If the infant responds differently dishabituates the researcher notes this This has shown that infants can differentiate between happy and sad music internal sensing device that indicates when the infant s rate of intensity of sucking incresase an increase sucking activates a visual auditory stimulus if the infant likes the stimulus it keeps sucking if not it sucks less Ex infants suck when they hear their mother s voice suck less when they hear
