I'm re-resurrecting it (I searched "messy bedroom"). DS is almost ten and already showing strong signs of messiness.
DH always had everything done for him (even now if he goes to stay with his parents. His mum goes through up his suitcase to get any dirty washing
. He is a very messy DH.
My DM used to shout at/threaten me with until she was blue in the face to get me to tidy my room, to no avail. I am a messy person.
The house is reasonable most of the time (less so at the moment because of work) but we try and keep on top of the communal areas for the kids' sakes.
DS doesn't seem to care about his room being a tip, DH tried the old bin bag line to which DS just replied ok, I'll just tidy away what I want to keep then. He can spend a full day in his room 'tidying' without really getting anything done (just ends up playing with something he'd forgotten about and rediscovered.
Seeing as we're not the tidiest people on earth, I don't know how unfair it is that we insist on him clearing his room, but I'm one of the my house, my rules bunch, so I don't want any extra mess from DS.
