When my daughter was a baby my friend painted the loveliest mural of a Classic Pooh scene (I'm an A.A. Milne fan). She had all the characters, but my favorite detail was that she had Winnie the Pooh up in a tree lying on a tree branch and pouring little stars out of a honey pot. She made the stars look like they were falling into my daughters crib. It was cute.
What about having Tinker belle flying over the crib and sprinkling fairy dust? Or a sorcerer Mickey doing something similar?
My friend also included a bunch of quotes from the Winnie the Pooh books through out the room. Do you have some favorite Disney quotes? From movies or Wishes or something? I have a thing for quotes and I like my kids rooms to be filled with messages about imagination, dreaming, good character, and enjoying life. Disney seems to have plenty of those kinds of quotes floating around!
Good luck on babies room! I'm also 19 weeks (well 20 tomorrow) pregnant, but in a rental and moving next year. No cute room painting for me this time...I think I'll make up for it by doing loads of shopping!!
