Would you go to a wedding if you didn’t know anyone?

I was invited to a wedding this weekend. But I don’t know anyone that will be attending. My mom was invited as well but I don’t know if she’s going otherwise I wouldn’t mind going. I’d just feel weird sitting by myself I’ll have my son with me to keep me occupied. But I’d really like to go because I’ve know the couple for years I use to babysit for them the only reason I stopped was because I had my son.
