Question
At one month old, what level of hearing development should a baby have?
Answer
A newborn’s auditory system is not fully developed and hearing is relatively weak, but they will have a blinking or trembling response to loud noises. By about two weeks old, infants can focus their attention on sounds, and by three months old, they can respond to the source of the sound. According to your description, your child is responding to sounds with physical movements, indicating that the child’s hearing is normal and there are no issues.
