My 8 y/o dd has a checking account at the "Bank of Mom" and has her allowance "directly deposited" every payday, which, coincidentally enough are the same as mine! :LOL I, too, had trouble remembering to give it to her on a weekly basis and then to play catch up. I took an extra check register and started writing in her deposits (she gets $8 a pay period or $4 a week)each payday (it is easy to catch up this way, cuz I *know* when my paydays are!) and then withdrawals as well. I've shown her how to keep a running tally. When she wants to buy something, usually a gift for someone, we subtract it from her total and then I buy it. I've explained to her that that is how real banks work. They don't necessarily have actual paper money on hand in the amounts totalling their customers' accounts, but it is often electronic agreements, transfers, etc.
She has chores to do simply because she is a member of the family. They are not tied to her allowance, but if she does something extra she can earn money that way. I wanted to give her a way to earn more if she wanted to. Sometimes the extra chores are done in payment of an energy debt, though! In other words, if her behavior drains my energy I don't have any left for doing my chores, so she must do some. I have also withdrawn "taxi fare" if I have to drive her to school, because she was not ready in time to catch the bus. Conversely I pay her if I make her late!
Right now her chores include feeding and watering the animals, we take turns cleaning the guinea pig cage, she scoops the cat box daily, and I change it every few weeks. She also changes the trash bags and takes the trash out to the curb, washes her lunch dishes if she took a bag lunch to school, sorts and takes her dirty laundry downstairs, I wash and fold it and she puts it away. She is expected to tidy her room daily and put away the clean dishes. She has just started to help with the cooking and dishes so we have yet to really work that out. Sweeping and mopping the kitchen floor, and vacuuming are my jobs, but she does those every once in awhile to earn extra ($2 for the kitchen, $1 for vacuuming the living room). She'd like to clean the bathroom, but I'm not ready to give that up yet! :LOL If I ever have to do her chores for her, then she has to do some of mine in exchange. Every once in awhile she likes to rotate things if she gets bored, but mostly she does the things she likes better.
Little dd puts her dirty laundry in the hamper and "helps" with some of the other chores. She particularly enjoys helping to feed the pets. She also helps pick up and put away her toys. I just bought her an 8 cube shelf from Target and put the baskets from her changing table in it. It has been a huge hit and encourages both playing with (she can see them all!) and putting them away. She doesn't get an allowance yet, but probably will soon since she is starting to show an interest in "peenies"!
