How many weeks pregnant will my baby start hearing her father talk to her?

4-5 months: The baby's outer ears start to develop after about 5 weeks into fetal development. The bones in the inner ear that transmit sound won't be fully developed until after birth but start to function at around the 4-5 month time.

After birth: Sense of hearing works after birth.
