Having baby stay overnight

Kristy
My husband and I are planning to go to a wedding at the end of October and having our baby stay overnight with a family member. He will be nearly 6 months old but I have anxiety about it :/ have you ladies done an overnight baby sit or planning on doing one? I am ebf too so I guess I'll have to freeze a bunch of milk for him to eat for 24 hours. Any thoughts or suggestions?
