Study: Babies cry at night to keep parents from having sex
A recent Harvard University study suggests that babies cry to keep their mom
exhausted and to keep her from ovulating. If she can keep her parents from
having sex, that will delay the arrival of a sibling who would compete for
food and affection.
"I'm just suggesting that offspring have evolved to use waking up mothers
and suckling more intensely to delay the birth of another sibling," Harvard
researcher David Haig told an NPR health blog.
Haig, an evolutionary biologist, published his interesting findings in the
current issue of the journal Evolution, Medicine and Public Health.
