Agreed. Libraries have books and DVDs, and you have things like the classical stations. You also have playgrounds and walks in the park, etc. (I'm also a parent of two young children.
Always doing wholesome stuff with your kids is certainly not easy or trivial, but there is a cascading effect here. If your child does not expect to be able to just watch TV all the time it's easier to keep them interested in other things. Once that expectation is burned in you'll be fighting it for a while. And once that expectation is burned in, a small child will _never_ say "I've had enough youtube, I don't need any more."
So I really don't want to be self-righteous about always doing wholesome stuff with your kids (we definitely do not succeed 100% of the time) -- but rather point out that letting them use addictive media has negative, cascading consequences that actually do make it harder for you as a parent. It's analogous to drinking to relax. You get relief now, and pay for it later. Not actually a good tradeoff much of the time.
