My first was a beautiful baby girl and we bought EVERYTHING pink... Diaper covers, butterfly papasan swing, you name it we had it in pink! We were excited and didn't care too much about what future babies would look like.
Now we have a baby boy and he is enormous so he didn't wear the newborn or smaller dipes too long and a lot of them were pinks and purples. He has outgrown almost all of the diapers I had for her and he's only 9 months now so as I buy bigger ones I get them in boyish colors when I can. I don't go crazy over it though. He rocks his pink and purple bumkins at daycare all the time and I put him in rainbow striped baby legs the other day and really got some looks! Lol...
