DS loves playmobil. He got a lot as hand-me-downs, and has gotten a lot more. We love the playmobil too and are not interested in getting rid of it.
We live 4 of us in 600 sf (no garage or basement or anything either). Its basically 2 rooms with a galley kitchen. We'll be here at least another 15 months. So playmobil just can't be all over the place. My mom wants me to get millions of plastic shoebox things and separate all the sets. I don't really like that idea-- too much separating, plus where will I keep all the shoeboxes? plus I love the way that DS mixes them together and isn't obsessed with them AS sets. He plays some awesome creative games where things overlap quite a lot.
But its just so out of control. I am always scooping random playmobil crap into baskets/bins. And I am ALWAYS finding playmobil crap around the apartment. And we have some big things- sure they are modular but still big- a castle, a research station, an egyptian temple...so they don't fit well in the smallish bins we have.
Any brilliant solutions to playmobil madness that are not major space hogs, are cheap , and can be maintained (with help) by a 6yo? I don't love using lots of plastic, I don't like the idea of big ziplock bags but maybe that would be a way to slightly contain them within bins?
Oh, and he has a 2yo sister who is quite interested in the playmobil and a very good deconstructor. :) It has spurred him to do a little less strewing them about than when she was younger (and when we had a bigger apt too). And there will be another sib joining us next fall, so a mobile baby here in about a year... I would like to have a whole new pattern in place about the playmobil well before that happens.
