Both my dc's (nearly 3 and nearly 5) have inherited packrat tendencies from their father. They will never, ever, consent to getting rid of anything - not that bit broken off the plastic tractor that's been missing for two years, not a single drawing, not the snipped-up pieces of paper or yarn, not that baby board book that's been chewed up and ripped in half and can't be fixed.
If my dc's catch sight of something going out - say, baby bottles, or a rattle, or even size 1 clothing - they dig them out again for a play (cue tantrum as nearly 3 can't get the size 1 shirt over her head, or does get it over, but can't get arms in). Cue more tantrums when I find the size 1 shirt in my washing basket again, after it has been kicked from one end of the house to the other and back.
I'm not talking about beloved teddies or lego or the elaborate artworks, obviously.
But that giant basket of soft toys they periodically strew through the playroom to discover just how boring they are? A third of the 1001 renditions of 'humpy-dumpy' in orange crayon? Ds's vacuum cleaner, that's missing all its parts which have broken off (ie can't be put back on) and doesn't work, even with new batteries? That scrunched up sticker book with no stickers cos they're all on dd's door? How do I get rid of that crap? I mean, treasure?
