My Music Prodigy

My son is currently trying to teach himself how to play the piano. He decided this 2 days ago. I taught him some basic fingering and 3 scales and chords. He has picked it up incredibly FAST!! He is now trying to pick out the music for Indiana jones. He has the lead part....but the bass (chord part) he is getting angry with. LOL Should I tell him that he shouldn't get so frustrated on his second day?
