I have 4 accounts: joint chequing account with my husband, my own personal account, savings and a daycare account.
All money received (husbands pay cheque, child credit etc) goes into our joint account. From this, we give ourselves spending money ($100 biweekly) that goes into our personal accounts to spend on whatever we want, no questions asked. We also pay our bills etc from this account. I put money into a personal savings account which is used for emergencies, trips, RRSPs, RESPs etc.
All daycare cheques go into my daycare account. I pay all daycare bills from this account (I purchase all items for daycare on a seperate credit card) and "pay" myself a pay cheque (which I transfer into my joint account). Any money left over is saved for tax time, daycare expenses and when I am down a kid etc. I don't touch this money otherwise and look at it as not even my money.
So, I have personal savings and daycare savings.
