Ok, so maybe IABU since I'm just embarking on clearing up, but...
Why do children generate so much endless, useless stuff? I'm not talking about tidying up after a particular activity, just the shedding of crap (not literally, they're potty trained) as they roam about the house.
DD(3) has a collection of handbags, filled with scraps of paper, pencils, sequins, notebooks, bobbles and general sparkliness which she trails in her wake like a Babe in the Wood; she also takes herself off to her room 5 times a day for a full change of clothes, which seems to result in the rejected items draping themselves forlornly down the stairs and over the carpet/furniture/baby.
Is this a girl thing? (Her slightly older brother's not quite so bad, limiting himself to reams of paper covered in intricate drawings and his Lego-floored bedroom).
