We waited until the homestudy was done, and then bought a few things. A crib (which was a waste of money as Yuna is STILL sleeping in her carseat and screams if you go anywhere near the crib with her!
) and a few gender-neutral clothes/blankets, etc.
We waited to buy most of the stuff, though. We got called about Yuna at 5:00 one evening and made a whirlwind Wal-Mart run the next morning before leaving for Texas -- bought the car seat, some GIRL clothes, diapers/wipes, formula, etc.
My cousin had also given us three HUGE laundry baskets full of clothes from her daughter, so we basically had what Yuna needed clothes-wise, already. She will be pretty well outfitted until she outgrows 4T clothes with just what we have already!
