Thanks! We got her 'birthday crown' at Babies R Us. They had matching dresses and shirts and stuff (and in blue for boys) but they didn't have the dress in size 12 months (of all sizes not to have for a 12 month old) so we just got the hat.
When she was 3 months, I bought her this little white dress, with a tulle bottom and it says "Princess" on it. I got 18 months, thinking she'd wear that size on our trip since she'll be almost 14 months, but it's so huge on her still. Oh well, a good excuse to plan another trip right!?!
