Best way to track child expenses?

[Daniel Trezub]

Hi, guys/gals!

I am wondering what is the best way to track child/wife expenses.

Example:
I have an Expenses: Dining Out account.
But sometimes my teenager daughter goes dining out.

What is the best way to track these expenses?
An "Expenses: Dining Out: Teenager" account
or an "Expenses: Teenager: Dining Out" account?

And I could ask the same for my wife's expenses or other types of expenses
(her clothing, her car, etc). How do you manage that?

Thanks!
