Residential care is like when you go to stay with a new family or house that is not your own. It's a place where some children or older people stay because they cannot stay in their own house or with their own family. These places usually have people who take care of you and help you with things like eating, sleeping, and taking medicine. They might also help you learn new things or play games with you. It's like having a different home and a new family for a little while.
