Millions of parents all over the world use technology to help them raise (and manage) their kids. Smartphones, tablets, video games, and TV are all helpful part-time babysitters for parents—especially moms—because they enable a caregiver to actually step away and breathe for a minute. At what point does tech use become harmful for toddlers? Many educational experts suggest tots shouldn’t have access to screens until they’re around two years old—and even then, it’s a limited amount of time they should be sitting in front of the TV or tablet. Other experts have different ideas, though. Angela Santomero, who co-created children’s shows like Blue’s Clues, Super Why, Daniel Tiger’s Neighborhood, and more wrote in her book that screens are beneficial for kids—in some formats, at least.
