Agree with not having it all at once. I have consoled myself with having a calm/clean-ish bedroom and lounge as the key to escaping! The kids stuff is in our living room and their rooms and we do a quick tidy it of an evening and on the weekend. xxx

ETA - It is easier now my 2 are older, much better in the last 6 months and I can see it will improve when they are both at school.
