At some point my stepson is going to come and live with me and my Husband. What is my role in this little boy's life?

We don't have kids in common yet but I love kids in general. My stepson is a 9 year old sweet boy he loves his dad a lot and is a well behaved kid. I want him to feel welcomed and want him to feel that our house is a safe place.
