First, get a set a clippers. They don't have to cost a fortune, the one I have retails for about $30 (US) and comes with scissors and a barber cape as well. If your clippers didn't come with a set of scissors, get those and a barber cape as well. (I've had my set for almost 20 years, so they do last if you take care of them.) Then, sit your minion down, and take a good look at his shaggy little head.

Next, we move on to the taper part. I won't lie, this is the hard part. Oh, and not cutting your fingers. That's not an easy feat either with a squirming kid. While they get their squirm on, grab the clippers and take off any strays that you may have missed earlier. One you're done with that, get your trusty scissors and convince your minion to hold still again. Put your comb almost tight to the head and draw it up though the hair until the bottom of the comb is just above the fade line. Using the clippers, draw them over the comb to cut away what sticks out through it. Do this the entire way around the head (except the front, or your minion will look weirder than usual).

At this point I usually take the clippers and with a bare blade even out the taper. It may be a bit bumpier right where the taper and fade meet up. Just make it look nice and even.
That's it. It takes a little practice, so don't get discouraged if yours doesn't look like they just stepped out of the barber shop the first time through. Remember, stylists go to school or something for this, by the time you do it about five times it will look perfect too.
