We had no play guns in our house (though I did as a child). Other people's children had to leave them at the gate.
We had plenty of crafts - which the boys and girls did together (including sparkly things and glitter). Both my boys wore pink (because it's just a colour) but I never bought any pink for my first child (a daughter) as it seemed to me to be strongly gendered.
We had no Barbie dolls or action men.
We did have construction toys and dolls etc, a sit-on tractor and a caterpillar.
We did our best to give our children choices and encouraged fearlessness and gentleness in the boys and girls alike but felt (and feel) the gendering is strong from outside the family whatever you do. We were not trying to raise gender-neutral children but wanted our girls to have the opportunities boys had and vice-versa.
Many girls learn from others that some things are "not for them" - too muddy, too high, too difficult and boys are called names for not being sufficiently "masculine". I still hear this in the street.
It is definitely the language in the very early days that, in my opinion, starts the gendering so that by the time we get to toddler groups the difference is embedded. I remember some research that found by 21 months children knew what group they "belinged to".
The "beautiful, helpful" girls or the "big, strong, clever" boys.
Gendered toys are the tip of the iceberg!
