What
Newborns
Know
A
new baby robin already knows three things. It knows to sit very still
when the parents are away. It knows to pop up and open its mouth to
beg for food. It knows to poop as soon as it swallows some food.
Babies feel the bounce on the nest when a parent comes
back with food. They pop up with mouths wide open. Soon they learn
their parents’ sounds, too. By the time their eyes open, babies
know their parents' voices.
