My friend hasn't really decorated. This is her #2 so they're using the same furniture and decorations as she had used for #1 (male). Everything is fairly neutral though so it could be anything. Her husband hasn't asked because he's really keen on keeping it a surprise but she says it's been difficult keeping to calling it "it" instead of he/she. She says her DH could probably guess from her slips but she's been doing her best to slip the other way and keep him guessing.
