Just buy a 2nd hand iPad gen 6 or 7. Lots of them in marketplace. Apple is still supporting those sets and will be for the next 3 or 4 years. For the time being, there are lots of games and self learning apps to prepare your son for school. And best part is, when the screen breaks, which it will, replacement ain’t that expensive or you can choose to buy another if it’s too costly in your area.
