answer:The norms were more fluid, for a glorious time in the late 70s and early 80s. At least it was if you look at advertising in the day. Compare the girl in This Lego ad to this modern Lego ad from France One is all about how kids can use Lego to encourage their own imagination – as a parent, having a toy in the first ad shown to me, I could say, “So cool! Tell me a story about it!” so even if I had no clue what she built, I could encourage her and also demonstrate my pride in her thought process. If she made a flower, out of a flower-making kit… well.. yay? But this is of course all “our own” fault. That is, people buy super-gendered toys for their kids, and instill in their kids the idea of rigid gender definitions. If people simply stopped teaching their kids that boys don’t like pink and girls hate getting dirty, this would all stop pretty quickly.
