In my experience as an organizer, as well as my experience as a mom, it has become abundantly clear to me that when it comes to toys, then less is more! I know I am not the first to say this, and I won't be the last.
I have always had more of a minimalistic view of toys due to a lot of different reasons: not a big enough space, not a big enough budget and just not wanting to feel like I live in a toy store. But, it also quickly became very clear to me that my kids actually benefit from fewer toys as well. I was most recently reminded of this during the summer while we were selling our house and moving. My kids only had a couple of toys each, and some books, but they contently played with what they had. They did not fight, and they did not nag or get bored as easily.
