Document Summary
When it comes to scent, 6 day olds (cid:272)a(cid:374) disti(cid:374)guish (cid:271)et(cid:449)ee(cid:374) (cid:373)other"s a(cid:374)d a(cid:374)other (cid:449)o(cid:373)a(cid:374)"s scent. Become very sensitive to the smell of (cid:271)reast (cid:373)ilk e(cid:448)e(cid:374) if the(cid:455) are(cid:374)"t (cid:271)reastfed. Oral exploration even starts before birth, fetuses in the womb suck their thumb. From 4 months on, infants begin to rub finger, probe, bang objects. Skin to skin care--studies show increase weight gains, cognitive motor skills, and time spent awake (well rested, a lot of learning happens) as oppose to preterm babies who do not receive that. Helps to facilitate bonding between caretaker and the baby. They wanted pregnant women to read a book (cat in the hat) twice a day for the last 6 weeks of their pregnancy. They tracked sucking rate, preferred (cid:373)other"s (cid:448)oi(cid:272)e o(cid:448)er fathers. Sucking would be an implicit measure: habituation - a decrease in response to repeated stimulation, revealing that learning has occurred.
