I have a lot of people in a pretty small house, and we can't get rid of much as we are using it. I am finally, as youngest dd gets bigger, getting rid of baby clothes and toys. Also sorting through some clothes that are getting too old or worn. But with lots of kids who go through different sizes at different seasons, and lots of good friends who give us great hand me downs, it is hard to keep organized. Also, only one bedroom of our 4, with 9 people living here now, has a closet!
Also it is hard to get rid of toys, they are all someone's favorite.
I am going to spend the next few months sorting and trying to get same size clothes together, rather than a collection of bins, boxes, and black garbage bags in the basement.
