I watched this in school as well (courtesy of a 16mm projector). It is like a precursor to Sesame Street. Wonderful! A Classic. Thank you for offering it. I have a copy that I treasure. I can't wait until my granddaughter (born in May) is old enough to watch it.
My daughters are 3 and only just now got interested in it (which is how I figured out I was sitting on 2 copies). Some local parents don't let their children watch shows or wear clothes with characters. For example, they can see a cartoon about a duck but not Donald or Daffy because they think it is too commercialized. But to me, if the child likes a particular character, they would be more interested in the topic.
You are Oh-so Wise, Sunflowers! The most insightful parents use what already exists in a child's environment to educate them, to reinforce the lessons they offer them. It is doubtful if after 75 years, the iconic, classic Disney characters have not gone away.... they are well enough entrenched in American culture (international, really) that it actually does the child a disservice to "protect" them from it. When I was in my prepubescent years, my sister and I agreed that we'd never give our kids candy and that they would think a carrot was a treat. Yeah, right! With their world full of Zotz and Nerds.. how could I compete? I did show them how much fun it was to crave a whole carrot with their teeth... that hobby waned pretty fast. Stick to your guns and listen to your inner wisdom, Mama. You will do well.
By the way, I avoided brand name clothes and instructed my children on the insipid subtleties of marketing to children when they were young. They would catch each other singing or repeating commercial themes. In a sense saying, "Ah-ha, you've been brain-washed!" I am against gender-typing, too. No princesses... except Mulan, of course.
