Nursery Themes....

What are your thoughts on nursery themes?  I am in that "nesting" but feeling kind of stuck.  I bought this awesome rug on Urban Outfitters one because I loved it and two because of the good price.   It has already come in it seems to be a bit brighter than this picture from the website.   I am debating on if we should paint Sadie's room or if we should keep it the white color that it already is....ahhh what to do?
