Document Summary
Newborns have an innate preference for sweet flavors: facial expressions. Smell aids in parent-child relationships: parents can recognize their infant by smell alone within hours of knowing the baby, macfarlane (1975) used a breast pad preferential method to determine if infants can. Starting day 5: oriented toward breast pad with mother"s milk recognize their mothers based on smell alone. Under 5 days: equal orientation to both. Day 6: can identify difference between mother"s breast pad and other woman"s. Week 2: can identify mother through other odors; i. e. underarm pads. Preference: mother"s pad, then other woman"s pad, then clean pad. Due to survival: neonates have a preference for the odor of their own amniotic fluid compared to another neonate"s amniotic fluid. Born with fully functional receptors for sweet, sour, salty, and bitter tastes. Infants are able to detect flavors in their mother"s milks. Skin is receptive to touch, pressure, pain, and temperature.
