Is it true that Women are more sensitive to high pitch voice of her baby ?

Is it true that women are so attentive to high pitch voice of their babies ?

I believe so. If by 'sensitive' you mean reactive. There is a physical reaction in mothers that listen to babies (even not their own) cry, scream (sounds, I guess).
There is some suggestion that a baby cries in the mothers 'tongue' because of exposure to her voice in utero.

WOW this is the reason why I say "Evolution made big revolution"

Babies are more reactive to the higher pitched voices (and other sounds).

Hence the high-pitched baby-talk voice adults adopt when trying to elicit a responce from baby.

This may be due the tiny baby eardrums having a high resonant frequency, so they are relatively deaf to low frequencies.
