Parents who have kids with the opposite sex, do you give them separate toys according to their gender or do they share toys?

Usually it starts out with separate toys catered for boys and girls but it never stays that way. By the end of the day, everyone is playing with everyone else's toys -- at least that's what happened in my family growing up. I played with my brothers' action figures and toy trucks and my brothers would find some joy in kicking my dolls around or feeding them to their toy dinosaurs haha. Sharing is fine, in my opinion.
