Being adopted means that when you were born, your parents couldn't take care of you, so they asked other people to be your new mum and dad. This means that they will love you just as much as their own children, but you won't live with them anymore. It's like if your mum and dad had to go on a really long trip, they would ask their friends to look after you until they came back. But in this case, your parents can never come back because they couldn't take care of you themselves. Does that make sense? Would you like to hear more about being adopted?
