It seems like normal behavior to me. Personally, I wouldn't mind if I went to someone else's house and their kids toys were on the floor, but I know it is nice to have a clean house. I have heard of doing a toy rotation where only a few toys are left out at a time and then after a certain time period those are taken away and new ones are added. That way the child isn't overwhelmed by all the toys and he actually plays with them instead of just throwing them around. My girls have a lot of stuffed animals. I took most of them away leaving only the ones that they really play with. They haven't even seemed to notice.
