I can't help but wonder how misguided parents are letting young children play with things like this.
Sure it may seem like it's good, but is it?
Is it teaching real world creativity, and real world skills, patience, rewards, or instant gratification?
I'd rather children be creative in the real world with real things using their hands than to stare at a flat screen tapping on things.
I'm guessing there's very little research around to tell you what they long term consequences are of introducing these things at such a young age.
I worry, whilst it might seem like it's a good idea, it may actually be creating more long term damage, attention deficit problems with real word things don't work as well, as fast or as easy as the electronic world.
