It's more parents' time, I'm thinking of mamya. With 2 girls and 2 boys, we had all options available and nobody was ever encouraged or discouraged to play with any of them. In spite of that... and also when I worked at a preschool, it is still more common how it is now (which is why it started that way).
If I am looking for my granddaughter this Christmas, birthday and end up walking down aisles of soldiers constantly, I will just come back and order from Amazon x
