To try this, you\'ll need to have the Mister Sandman perk activated, which will mean you have to be at least at level ten. You\'ll also need a sneak skill of at least 60. If that fits your character, then travel to Andale. Andale is full of kids that can\'t be killed (killing kids in Fallout 3 is an impossibility). During nighttime, when everyone in Andale is sleeping, break into various houses and kill the kids while sleeping using the Mister Sandman perk. They won\'t die, but you\'ll still be rewarded experience for having killed them. You can then repeat the process over and over again for infinite experience points.
