Most women I know want at least one daughter. And most with one of each claim girls are calmer and less destructive as small children. I'm not sure how true that is, do boys have higher testosterone even as toddlers? My DD is high energy and always bouncing off the walls!
Nothing to do with testosterone, but gender expectation. Boys have so much energy and need to run it off. Girls like colouring and craft so will sit nicely and do that.
People watch a bit. It’s often obvious im family restaurants. Boys will be allowed to get up and down, run about between courses, get a bit noisy. Girls will be sat at the table, expected to engage in conversation, draw with the pens, and will be admonished for any rowdiness.
Boys are taken to the park and allowed to free play, often roughly. Girls are warned to get down from the top of the climbing frame and to be careful. They’re often in impractical dresses which hinders proper physical activity and/or have warnings not to get their clothes dirty.
By the time they’re 3 or 4 they’ve had years of this behaviour modification, and are behaving to stereotype all by themselves.
But it is completely natural for girls to like pink. It’s not societal at all, it’s pink brain.
