Underexposure on kids portraits

I asked my teacher for advice on how to make my portraits better.  In particular, the photos of my nephews in the post below titled "Favorite Faces of 2009".

He suggested an external flash.  I guess that means I need to move the speedlight up towards the top of my list.

He also said that a happy medium would be to take two pictures, one with the exposure on the kid, another with the exposure on the background.  Review the images to see what the shutter speeds are (this is best to start in AV mode, where you can keep your f/stop at a constant number.)  Look at the shutter speeds, and flip the camera to manual mode.  Dial in a number for the shutter speed that is between the two of them (say the background was at 1/300 and the kid was at 1/100, you would dial in 1/200 of a second in manual mode).  This might give you a happy medium, slightly underexposed kid, with a slightly overexposed background.  Make sure to keep f/stop and ISO the same as the test shots.  He said that this would take a little longer but might help out until I can buy a flash. 

Another option is to dial the shutter speed (in manual mode) a little faster (to keep the background exposure more accurate), and then use the pop up flash.  From the menu, you can adjust the setting of the flash.  Start light (ex: 1/8 to 1/4 the power) and increase it if the kid is too underexposed.
