I Loved From Generation to Generation, which I saw at Harriton High School in Biology class back in 1964. It's dated, but I should like it if I DID see it now. It involved a farmer, his wife, and their four-year-old son, in Pennsylvania. The farm was still out of reach of electricity, so dependent on smoking lamps for illumination. The film showed the actual reproductive process in animation form, but the scenes showed the family trough the four seasons, living their lives, including the wife while pregnant. There were love scenes, but what I found delightful was the sweet background music. For an educational film, this was superb indeed!
