My kids get a fair share of unsupervised tablet time.
And they seem to know 10x of what I did at their same age.
My son is 9, watching endless Geometry Dash tutorials, and making his own levels. He loves it, and he loves to show me his work.
Tablet time will become an extension of your home life.
If you have good discussions - encouraging curiosity, fostering creativity, challenging their approach "Why did you design it this way?" - the kid and the algorithms will follow that lead.
