Though kobolds are quick to mature out of the egg, they still have a period of childhood in which they are very weak. Particularly ruthless tribe leaders may send them as waves of expendable warriors in the way they treat their adults, but this is so bad for the future of the community that only the evilest and short-sighted would do so, and they would most likely be turned on even by the lawful and nonindividualistic tribe members.

This child is destined to become a miner, like many kobold commoners. Kobold children training for different professions are likely to have different feats and skills, but these are unlikely to come into play anyway, so this stat block probably can be substituted for any kobold wyrmling without modification.
