I need to at some point soon, probably not till the end of the holidays (as once schools back DDs will be in school uniform and not use the clothes so much. Go through all their lovely clothes and at least half them. I don't want to. None is stained or tatty or too small, so all perfectly functional. But we are moving house and having a baby and they are going from having a big bedroom each to having to share an average size double bedroom. Currently DD2 has 2 double wardrobes and it's full
although that does include using the shelves at the tops for toys etc. And it also includes her bedsheets etc.
DD1 currently has 1 double wardrobe and 2 large chests of draws, some small draws in her midsleeper bed and trousers and bedsheets are kept in the cupboard again within the bed.
None of this includes shoes. They have a large washing basket full of shoes each 
I don't know how to do it. I KNOW They have too much. But I and they like it all and use most of it. I will get rid of most of the t-shirts and trousers as they pretty much live in dresses, but I don't know how to cut down on the rest!
Any tips/support would be good.
