Babies hearing development during pregnancy

Babies hearing development during pregnancy

Hearing development during the first trimester

Already between week four and five of the pregnancy, cells in the embryo start to arrange themselves into the baby’s face, brain, nose, ears and eyes. Around nine weeks, little indentations in the side of the baby’s neck appear as the ear is forming on the inside and the outside. The indentions will soon move upward and develop into your baby’s ears.
