With an adult in the same room, I don't really limit my daughter's exposure to tech-including educational videos and educational games. We started baby signing time videos at 12 months. Age has a tablet of her own downloaded with mommy approved games and likes to move around her apps and everything. We let her operate the dvd player with us RIGHT there. Etc.
As a parent I don't want to set time limits so long as electronics are not all consuming. Since it isn't a treat, my daughter will actually turn down time on her tablet, etc and prefer to color instead. It's just another toy to her.
