Currently my purse is a diaper bag. Or it is a passport wallet I use for everything.
Diaper bag has everything for Jack. Inside for me are keyring of store savings cards, coupon holder, lipgloss, chap stick, and pens + wallet.
Wallet: holds IDs, credit cards, checkbook, registry for checking account, coupons, phone, cash, coins and pen. (I have a large PASSPORT wallet as it is formally named)
