Why did boys wear dresses like girls when they were little and didn't cut their hair until they were six or seven years old in the Gilded Age of America?

There is a custom on their side. When they were young, boys wore dresses like girls and girls wore dresses like girls, and that was their custom. You don't get a haircut until you're six or seven years old, and then you think the child is old enough to understand. If he let them wear skirts again, they felt a little bit embarrassed. Until after the age of six or seven, they will be normal haircut, to wear some normal clothes.
