You can log into the Amazon account, download the books you want him to have, deregister the Kindle, and the person cannot use the internet or buy books until they have re-registered.
If I didn't do that I would use the password so that the child had to bring the Kindle to me to be able to start reading and I could monitor his activity. If the kid ordered a ton of books, I would return them to Amazon and the child would lose his Kindle privlages for a long time.
