It just makes sense, children are weak and need a lot of care and protection, so most other animals reach maturity much faster than humans. Chimpanzees, for instance, have a very long rate of babies staying with their mothers and it's only five years. We take care of our kids until at least sixteen and often beyond. These little guys," he nodded to Erica, "are a few months old. Dragons generally leave the nest fairly early."
