We don't do an allowance... No one gives me money to clean my own mess, so I don't feel right about giving one to my kids.
We don't have "set" chores, and the chores that I do require, I don't call them chores.
Ds (5 yrs) is expected to take care of his own dishes, atleast at breakfast and lunch (just putting them in the sink), ensure that his laundry is in his laundry hamper/closet, pick up his toys, set the table, and, with help, bring his laundry from the hamper to the laundry room, fold certain items (wash clothes, socks, etc), and kind of, anything else that I ask him to do.
He has his own little vacuum thing, and likes to help with that...
I used to require that he make his bed. Somewhere along the way, I decided I felt hypocritical. I don't make my bed... so why would I require that he make his? Yeah, yeah, I should make my bed. But it's difficult with this whole co-sleeping thing right now. Bed is on the floor, no real blanket. So... I'm not making my ugly bed. (Shhh, don't tell my mom!)
