We love those kiddo smiles and in order to keep them, I am super efficient with my family photography! I don't see any reason we need to make everyone keep it together through a 60+ minute session. I'm a 30-35 minute girly, myself. I know those "nice shoes" are uncomfortable for little feet, everyone is hungry, someone is probably sick, and bedtime is in 25 minutes. Let's go have some fun and get this done.
