I need your best tips. There's only so many toy boxes and toy bins I can buy. Her room just feels so disorganized. I want to make it a little easier for her to clean up and keep clean. What's worked for you?
Does she have too many toys?
One thing I found with my children was that I needed to keep the number of toys down to something manageable - and something THEY could help keep tidy themselves.
That meant one plastic bin for small stuffed toys. One bin for building blocks. One for Duplo. One for train tracks. One for Barbies/dolls. One for cars and other things with wheels. And one for assorted small toys.
The plastic bins sat on low-but-deep IKEA shelves, all easily reachable by my children. Large stuffed toys, tractors, etc, could sit on the shelves beside the bins. Books could be stacked neatly on a shelf.
I wrote labels in big block letters on all the bins - hey, it's an opportunity to teach reading skills, too!
I also put in hooks at their level so that they could hang up their own clothes instead of throwing them on the floor. And I put down a mat for their shoes. It had SHOES written on it, too.
My rule was that everything gets put back in the correct box when you're done playing with it. Nothing is left out overnight except projects that you're still working on (like a giant snaking train track, or a Duplo castle, etc...).
When they were toddlers, we always cleaned up together and I used it as a sorting exercise, teaching colours and numbers and counting. Sometimes my children would refuse to put their toys away, telling me I could do it myself. That's when I would shake my head sadly and tell them that my job was making sure they did the right thing, no matter how long it took. Then I'd take them by the hand, walk them over to a toy, put the toy in it, then walk them to the correct box. Repeat as required. The children only tried this a few times - I'm FAR more persistent and patient than they are, and they quickly realized it was easier to just clean up. Usually, it was fun.
Heck, they're teenagers now and when I go on a cleaning spree, they still know it's best to just do what they're told, without argument. (Although I noticed my son took the phone with him when he was cleaning the bathroom the other day - he was calling all his friends to see if he could escape to their house!
