My kids are like hoarders or something, I swear. Their rooms are just so full of...clutter for lack of a better word. Both my husband and I tend to be pretty neat people so this is driving us batty. It's not even like all toys or anything. Candy wrappers, rocks from the backyard, part of a shoelace (?!?). Whenever I try to talk them into getting rid of some it, they claim some sort of sentimental attachment to it. Help!
