Oxytocin

You may play Oxytocin during times of social
bonding (such as "cuddling").
{t}: Promote bonding with any Newborns you
control.
{1}{r}: Stimulate uterine contractions if pregnant
and in labor.
It's created in the hypothalamus and released
from the posterior pituitary. Even though it
makes you feel warm and fuzzy with your kids, it's
also what causes painful contractions during
labor. Fun...
