Kids have incredible motivation and time far beyond any adult.
If you spent 1 hour a day learning a new language most people would consider you a dedicated language learner, but a child spends almost every waking our in contact with language.
Children also have to keep up with their peers and siblings (and adults after a little while).
If I had unlimited money I'd love to do a research project with adults in full immersion environments similar to what children experience for years at a time with no chance to 'run away' to their native language.
