What do you think are the benefits of parent-child games?

Playing parent-child games with children is conducive to emotional communication and allows children to learn knowledge in the game. My child is 3 years old. I usually like to play seesaw with him. I sat by the bed with my feet on the ground. The child sat on my feet and faced me, holding my calf to prevent falling. I teach children ancient poems or children's songs. When he answered correctly, I raised my leg and let the child tilt up like a seesaw. He likes playing and remembers a lot of knowledge in the game.
