Can parents do anything during pregnancy to make their baby gain knowledge?
Is breastfeeding better than bottle-feeding (with infant formula)?
Do infants start seeing color from birth and if not how do we know that babies are color blind and when do they stop being so?
Breast-Feeding vs. Bottle-Feeding
Common challenges of Breast-Feeding
Sore nipples
Low milk supply
Oversupply of milk
Plugged ducts
Breast infection (mastitis)
Fungal infections
Nursing strike
Inverted, flat, or very large nipples

What is "learning" to an infant?
"Cat in the Hat" study
Increase in heart rate when hearing mother's voice
Music helps the mother relax
Study where babies' brain activities showed neural signal
Reading/talking aloud helps with bonding
There is a lot of grey area
Researchers can't agree
Not really feeding your baby knowledge
Right Out of the Womb
At what point do babies recognize their parents?
Sudden Infant Death Syndrome
Why does SIDS occur?
“The sudden death of an infant under one year of age, which remains unexplained after a thorough care investigation, including performance of a complex autopsy , examination of the death scene, and review of the clinical history.”
Cause unknown
Leading cause of death for infants aged between one month to one year in developed countries
SIDS Rates in the U.S. = .57 per 1000 live births
More common in boys than girls 60/40
African Americans, Native Americans, and Alaska Natives are 2 to 3x the national average for SIDS
Premies have 4x the risk of SIDS
Young mothers tend to have more instances of SIDS
Risk Factors
Maternal smoking during pregnancy (decreased lung volume and compliance and decreased heart rate variability to stress; nicotine also has negative health effects
“If in-utero smile exposure was eliminated, 1/3 of SIDS deaths could possibly be prevented”
Soft bedding and soft surfaces
Overheating/heat loss from face
Bed sharing
Sleeping in prone position
Limited arousal/high arousal threshold during rest
