I feel like 80% of our housework that doesn't get done is picking up. Now that DD is almost 5, I want to start this as a chore. Usually its not big things (aka if she got out her blocks, we ask her to put them away and she understands). But if she carries a purse out of her room, it gets left. A trinket that comes home from school is left on the counter. I want to sweep it all up and throw it away! Any suggestions for getting her to better pick things up?
