Loan them copies of the books you've read - when you're done. Get them hooked and then make them fend for yourself. You may find it very annoying that they won't do the work themselves and just ask & ask (don't just send them to ask elsewhere

), make it so they learn WITH you and then are OK.
What you'll want to do is to steer them in the right direction so they do a little themselves but you don't need to do all the work. If they do a decent amount of the work they will learn better and you and they will be better rewarded...
