Any mummies pretend to cry to see your toddler's reaction? Not crying with tears just the sound. Will your toddler cry when he/she sees you cry?

Some how my kids know that i am fake crying, they will beat me back, But there is once during an argument with my husband, i literally broke down crying, my elder also cried with me but at the same time comforting me. Kids know whether our cries are real or fake
