Ready to get rid of some of your kids clothes and needing needing clothes in their new sizes. Take a look at ThredUP Used Kids Clothing. You put together boxes to send to others, and you can pick clothes that others have put together. You just have to pay for shipping, from what I can see. I haven't used this site since I am not ready to get rid of any of my kids clothes yet, but it might be worth looking into for others.
