You are not alone at all! I've been fighting this for 9 years! You didn't ask for advice, so please ignore if you wish, but I found something that helps around here. It's called the Sunday box. I gave my kids a 2 day warning of "whatever isn't put away on Monday will go into the Sunday box, you won't get it back until then. The first week I had two mesh bins full and very sad kids, after that they've picked them up most of the time and I haven't had to nag at all. I wish I could take credit for it, but it's how one of my friends' moms handled 3 kids and a daycare in her home. I love not yelling anymore and not tripping over things. Good luck!
