Child at Heart (Fallout 3)

Child at Heart is a Fallout 3 Perk.

The Child at Heart perk greatly improves your interactions with children, usually in the form of unique dialogue choices.

Little Lamplight
The Child at Heart perk is particularly useful in Little Lamplight, where several children are present.
 * Mayor MacCready will give you access to the town.
 * Mayor MacCready will also allow you to trade Buffout and strange meat for Cave Fungus.
 * Biwwy will give you the Wazer Wifle for free.
 * Eclair (the chef) will trade with you (has 1 Cave Fungus for around 50 caps).
 * Knick Knack will trade his goods with you at a discount.

Other Areas

 * Maggie in Megaton will tell you the combination of Billy Creel's safe.
 * Bryan Wilks near or in Grayditch will give you the key to his father's weapon and ammo stash (thus avoiding a speech check, although it is already easy to pass before you get the Perk and you won't receive XP with this method).
 * Rachael and Ralph will let you enter The Republic of Dave, but Flower and possibly the other children will let you in without the perk.
 * James Hargrave in Rivet City will steal ammo for you.
 * Derek Pacion in Canterbury Commons will tell you the weaknesses of the AntAgonizer and the Mechanist. You can then convince them both to stop the fighting after passing a speech check.
 * Dean Dewey in Roosevelt Academy will ask you for a hallpass once he is activated at a terminal. You can convince him that you forgot your pass with this perk and he will not go hostile.
 * Penny in Paradise Falls will be convinced to leave Rory McLaren behind during Rescue from Paradise This can also be done by a high speech level and is not necessary.
 * The Mechanist will be convinced to stop trying to be a hero after the player obtains the AntAgonizer's Costume, resulting in not only keeping the costume, but obtaining The Mechanist's Costume as well as positive karma.
 * Sapling Yew in Oasis will tell you Harold's fear (fear of fire - burning to death).
 * Machete (character) in Canterbury Commons will acknowledge that she was on her way to Big Town but decided she'd rather explore and ended up there.
 * A tribal in Point Lookout will give you the fertilizer shovel (this can also be done with a speech check).
 * Kenny in Point Lookout will alow you to store your gear and sleep in his cave, without having to search and return his Kenny-Bear.
