All moved in...and don't know where to go!

Baby girl has a new dresser in her big girl room, and today I moved the last of her clothes out of the nursery. So she is officially moved into her new room. I decided to take the posters that were hanging in the nursery and put them in the playroom (AKA our old study) so now both the nursery and baby girl's room have empty walls. I am leaning towards a garden theme for the nursery given the fact it already has green walls but am at a loss at how to decorate baby girl's new room. Her dresser is white, her quilt is lavender/white stripes and her sheets are floral so I guess I have already started down a cottage/shabby-chic theme but am having trouble visualizing the rest. Any ideas?

Who knew a child could love Mary Poppins this much? I have had to limit the amount of times we watch it to just twice a week. I can't complain too much because I have always loved that movie so there are worse things I could have to watch over and over again. Unfortunately, Mary Poppins now has to compete with Wallace and Gromit, and I am rooting for Mary Poppins!
