Just popping in to say that I am well on with this and it's a brilliant method of decluttering. Usually I declutter every 6 months, never got down to this level before.
I have ditched about ten large bin bags at least. ( I didn't think I was that cluttered)
For those of you with toys, when mine were tiny I had only a few types of toys. It allowed them to play much better.
You are bringing them joy if they can get to and play with their toys. I stored toys upstairs and just put all of the toys into boxes by category. ( duplo, trains, dolls, cars, farm) They would have one or two categories out in the morning or afternoon. They had to be packed up before we changed them.
They still play like this now, they are really excited to bring something down and set it up/ play with it, Rarther than it just becoming part of the furniture.
Bag up all the random crap and pop it in the loft, you can bin in when no one asks for it.
So I have remaining,
Wires ( dh job)
DVDs
Photos, sentimental.
Garage
Loft
Children's games/ children's desk
Every single area I have done has stayed perfect!
