How did you celebrate your child's adoption?

We have an 8 year old biological son. We've had our daughter since she was a few days old. She's 13 months old now. We finalized her adoption today, and we couldn't be happier. We were thinking about having a small party to celebrate her adoption. Invite our closet friends to a kid family restaurant, or possibly have a BBQ at our house. I'm not sure yet. What did you do to celebrate your child's adoption? Please be polite, thanks.
