I really want a pot noodle now 
With both mine they were in white for ages as we didn't find out what we having. Its a really useful thing to do as you can easily pass onto dc2 no matter what sex they are.
I also said no to the whole pink thing. It didn't last. DD1 is 5yo and for the first two years she didn't wear anything pink. Then at nursery pink became her favourite colour
so that put an end to that. With dd2 I just embraced the whole pink/character thing and lightened up.
The character thing gives them such joy it would be a shame not to allow it. They have character pj's and knickers which they both adore. We are not swamped by princessy things though, and dd1 is as likely to climb a tree as she is to put on a princess dress and dance around the living room. I think somehow you have to strike a balance.
This time round though I am looking forward to finding out the sex before I buy anything and having a baby dressed in colours for photos.
I'm also wondering if it will make a difference if I know the sex? After 20 wks I will know whether to say 'him' or 'her', and I probably know the name. It will be interesting to see how that feels.
I wouldn't change not knowing for my first two dc though. The moment you find out after the birth is so special IMO.
