Oh, absolutely - I grew up with it also!  It’s a fairy tale, and factual rigor is inappropriate.  Seeing it as an adult I can appreciate production details, such as keeping the music entirely “in-house” - at the ball, not only was “My Favorite Things” reworked into a perfectly serviceable waltz, but the music for the “Laendler” folk dance was “The Lonely Goatherd” with a different time signature, just as was “Good Night My Someone” and “76 Trombones” from The Music Man.  I am vastly entertained by such things!
