I think that once parents become the OS devs specifically for their own children (or at least app devs) the tablet becomes less like a pacifier and more like a ball game between the toddler and parent, as each throws new stuff (metaphorically) at the other.

This is nice that you're walking them through it but I wonder why you'd need a tablet in the first place, then? It's better to sit with them in front of a monitor with the proper posture and viewing position.

Nice, you're managing a curriculum now.
