I didn't buy big ticket items but after my third loss I bought a gorgeous but ridiculously expensive little outfit. Did it as much as anything to give myself a kick up the bum to get over myself and keep trying. I think there was also a little part of me that thought if I've spent this crazy amount of money on one thing then the universe just HAS to give me a baby ;-)

I am very superstitious though and in the early stages of each pregnancy have never even walked into a baby store, just in case
