Hello Meghan,
I didn't see the double post, so here is the answer to your BirthDate inquiry. In essence, yes, you can add a field to the table, call it a different name like BirthDateCamper and use it in the screen. It won't be in QuickBooks to sync, but you can use it in customized reports in Method.
I see you have two options. The Customer doesn't have a birthday because it is usually a corporate entity. Method users will use people's names for the customer names to keep accounts straight. With this in mind, the parents can be customers and have children tas contacts. In this situation, you can put a BrithDateCamper in the Contacts table. If you are using each camper as a Customer, you can put the BirthDateCamper onto the Customer screen. Remember to update the NewCustomer screen as well.
