Smartphones have become an indispensable part of modern life, even when it comes to raising a child, but experts warn against children's first exposure to the device at too young an age.
Ahn Dong-hyun, a professor at Hanyang University College of Medicine in Seoul, said, "In academia, it is recommended that children should not be exposed to video devices including smartphones before they reach 36 months. Unilateral stimulation of visual and auditory senses at this age can be harmful".
Until they reach the age of three, babies' brain neural circuits form rapidly, and they need to receive well balanced stimulation of all five senses. However, smartphones only stimulate the visual and auditory senses.
