Nursery puzzles

Life is full of questions I hadn't expected to need to answer.  For example, what do you put in a nursery?  We've moved the spare bed out of the spare room and into the attic, so that's a good start - there is now room for other furniture in there.  Matt's going to do a bit of a paint job and we're getting Little Miss and Mr Men stickers to go on the wall, so it will look like a room for a baby.

But then what?  I guess we'll get a cot from somewhere.  But I really have no idea what else to put in there.  Baby stuff shops seems to sell changing tables, but it seems a bit of a waste of space when there's a perfectly good floor for changing on.  And nursery furniture sets also seem to often come with a wardrobe, but I'm not really sure why you'd want a wardrobe for baby clothes.  It's not like it's going to have full length dresses for a long time, if at all.  

I'm tempted to leave it until the baby is actually here and we can work out what we need ("wouldn't it be useful to have somewhere to put all this [insert name of things which need storing]?" "yes, let's go and buy a [insert storage device]") but the impression I get is that you only have half an hour at any one time to do anything with a small baby.  Not long enough to work out what it is we need, never mind find it, buy it and put it together.

Planning for a baby is really quite puzzling.
