The fact that newborns can recognize their mothers based on smell alone within a few hours after birth suggests that olfactory information is in place before birth. This means that the olfactory system of the fetus is developed enough to recognize the mother's smell. It also implies that the mother's smell is present in the amniotic fluid and that the fetus is exposed to it before birth.
