The ability to localize a sound is supposed to be related
to the distance between the ears compared to the
wavelength. So babies should have a harder time
localizing low frequencies. When women are around babies
they immediately adopt a certain instinctive manner of
speech which involves raising the pitch. Are baby heads
so narrow that raising the pitch is necessary for the
voice to be localized?

More likely its the smaller size of a babies' hearing
apparatus that makes them more sensitive to high frequencies
than low. Of course that includes the head, but baby heads
are disproportionately large.

I would have thought it to be some sort of a natural adaptaton. They are
tuned to their mothers voices, just as women are tuned to the sound of a
baby's voice.
