I feel your pain. You need to have boundaries of where to keep the toys, like a closet so the stuff doesn't take over and drive you insane. If it doesn't fit there, get rid of it and don't feel guilty (easier said than done). That sucks they ask where things are they have given. You may have to take up lying and say "it's around here somewhere". You just have to donate and try to guide them to give less and less and less. It really adds up and becomes a nightmare. Teach your kids to put stuff away after they play with stuff otherwise everything will be dragged out all at once and you won't be able to walk around easily. Unfortunately people giving too much stuff has become an epidemic and they often cannot stop even if you ask. You learn to recognize good toys from bad ones (good ones are stuff like books, puzzles, wooden toys, art supplies, dolls, cars, legos, musical instruments; bad toys are anything made of stinky plastic, stuff that breaks, pens that are not washable, anything that makes a mess, anything with batteries, anything that makes noise, tons of little choking hazard pieces, humongous molded plastic furniture, stuff with a character from a tv show, stuff that you can collect more and more of, etc). Decide what you like and make room for that, and the other garbage get rid of.
