Custom Customer Profile or Custom Line Item?
I'm looking for some advise from someone who may have more experience with Commerce than I do. I am creating a store for children's class registration. I would like to capture some information about the child at checkout, like Name, Age, Gender etc. I'm not sure whether to create a custom customer profile to store this info or to put it in custom line items.
A new profile type seems like the best option, but what if the parent has more than one child? The custom line item seems cumbersome.
Is there another way of doing this that I am not thinking of? Thoughts?
