Mine can be the same. Mostly their toys that could be broken no longer exsist anymore, only the strongest have survived. If they are being particularly restless and destructive and the weather is good enough I try to do messy play with them outside. Like mix up cornflour, water and food colouring give them containers to tip it into and send outside and don't look at all the mess they are making out there. I find that if I give them one area where it doesnt matter what they do, they seem more able to keep the inside clean.

I too find all the destruction and lack of respect for stuff really frustrating, but I guess they don't yet have a concept of when its broken, its gone.
