Thanks for all your replies there has been some great suggestion that I will definatly try.
At present all the toys are 3 of the stepped toys units from Ikea, 2 in lounge and 1 in their room. They have bed boxes under the bunk bed and Roxy bed for books, dolls, lego and all their bedding. There is no more floor space for storage as it is a small room but I hadn't thought about putting a load of shelving in for books etc

so thank you. That would free up some space under bed.
I know it is my own fault it is this bad as I am a bad hoarder

don't like getting rid of anything incase we need in future as wont have cash to replace etc but it has got to the madness stage. I have been helped on that front in that a couple of friends have hit hard times so I am passing on everything I can to them so clearing some stuff out and dont feel bad about it as I know it is appreciated and will be used iykwim.
I think like you have suggested I need to focus on one room at a time as I had been going from room to room trying to make it look ok but not actually getting anywhere so will do it 1 room at a time.
Thanks again ladies
