Auditory toys for children under 3 years of age are designed to develop children's auditory perception and hearing. Such toys may contain various sounds, noises and music to attract children's attention and stimulate their auditory processing. Examples of auditory toys can be musical instruments, rattles, music boxes, sound blocks and interactive audio plays. By playing with auditory toys, children can improve their auditory perception and processing, develop their cognitive skills and increase their self-confidence. Auditory toys can also help support children with hearing difficulties or other hearing problems by helping them improve their hearing skills and train their auditory perception. Parents and educators can use auditory toys to provide children with a fun and interactive way to enhance their auditory awareness and encourage their development.
