when will ypu start letting your child use electric gadgets ?

Pediatricians generally recommend kids don't start using electronic devices and screens until they're at least 3 and no more that 30min a day if they're alone. If you use the device or watch the screen together the time can be longer and the negative psychological affects can be avoided. That said, all of this media can be addictive to very young kids, so moderation and parental guidance are key.
