I am having a little girl and couldn't wait to start on her nursery as soon as I found out the sex! I love girly stuff, but didn't want to do the traditional pinks and purples, so I went with Tiffany Blue with white and pink accents.
My inspiration was a picture in Pottery Barn's magazine with the CocoDot nursery bedding and tiffany blue walls.
My favorite thing in the room is probably the wall decal.
Get a color palette and stick with those colors.
