I did my bubs room early on, (I had extreme back problems on and off and wanted it all done in case it got so bad that i couldnt do anything) i painted it at 17 weeks, set the cot up at 19 weeks and bit by bit washed all the clothes and blankets (they were all in storage from DD1). Everything was pretty much done by 25 weeks which was good and bad because i could barely walk but i also got bored of having nothing more to do for bubby.
