In the last year we've let her watch some YouTube cooking videos in a supervised setting, and she and I have started working thru some educational titles on my old Apple IIgs. We've tried very hard to avoid "twitch" stimulus, if only because I have an unscientific belief that such stimulus "dulls" ones' sense of novelty. (I know that I find myself struggling to deal with "slower" movies and video games that I enjoyed when I was younger.)
As a parent of two young children:
(1) It's not “will now” as in something that hasn't been true already.
(2) It's not “as young as”, if they are around, children will ask for them younger (much younger, like, before they have words, when asking is done by gesture.)
(3) It's not “instead of licking the floor”, but “in addition to licking the floor”. Also, they'll lick the tablet.
The hardest parts are to transition away from the tablet. We always supervise and use a countdown and replacement with another favorable activity (5 minutes and we're going to put the ipad away and play with trains.. 3 minutes.. 1 minute.. time to play with trains) and then following through even if they get upset. We also only allow like 15-20 minutes at a time (the longer they play, the harder it is to pull them away, such is addiction) and only a few times per week (if that). We also are not afraid to say no to tablet time and redirect to another activity.
I think kids can learn a lot from technology but it requires parenting to minimize harm.
