Taste and Smell
Captions available
The idea
Taste and smell begin before birth; newborns distinguish sweet, sour, bitter and salty, and show distinct facial expressions within hours.
In practice
A six-day-old turning toward a pad scented with its own mother's milk.
Where people slip
The fetus swallows amniotic fluid from about week twelve, and newborns favour flavours met there, such as garlic or vanilla.
