I work with a designer that has something like 20+ years of print experience. We make web sites. It's true that some habits are hard to break, like wanting pixel perfect shapes and alignments, which of course doesn't work too well with today's needs of responsive design, or mobile first interfaces. But, after a basic introduction to the fundamentals of modern web design, the guy has come up with some great ideas, elegant and easy to navigate... And can still do posters flyers etc. He is now even getting into 3d stuff for animations. Point is, learning is incremental, and it's always possible to extend what one knows in new directions, if one is of curious mind and willing to change. Now, concerning toddlers and tablets... the thing is, we are governed by the physical world in which we live. It's very important on a mental but also motor level to have a good understanding of that. I mean things that adults take for granted like balance, dexterity, hand eye coordination, a subconscious understanding of gravity, etc. These are actually learned by trial and error, if you've ever seen a toddler stack blocks or learn to throw you'll have seen this in action. During this period of learning about the world, having regular interactions with objects that do not follow the same rules is confusing to very young children. This is not just my opinion but something which many child psychologists agree on. Again I'm not against tablets, but better not to introduce them earlier than 3 or 4 years old at the earliest. I think that still gives them plenty of time to assimilate 21st century technology and think of the next big thing in 20 years. Which I probably won't understand ;-)
