2-year-old brother takes 8-year-old brother's toy. What if my brother doesn't give it to me?

Looking for mom and dad. My 2-year-old brother is a guest at home and wants to take his 8-year-old brother's toy. If he doesn't give it, he can go to his parents for mediation. Toys generally refer to things that can be used to play. Toys are often used as a form of entertainment in human society. Toys are suitable for children, especially for young people and middle-aged and elderly people.
