How long does it take for a premature infant to develop sound localization?

Preterm infants typically begin to respond to sounds after about one month. Due to their premature birth, a baby's hearing may not be very sensitive. Appropriate activities can help promote the development of their auditory system. Showing black-and-white cards frequently can benefit visual development. Because preterm infants are born earlier than full-term babies, they may lag behind normal infants in certain aspects, resulting in delayed development. At this stage, it is best to engage preterm infants in suitable exercises, which will gradually help restore their hearing and vision.
