My breast pump! If you are going to breast feed, use one! It will free you up! Medela has a great website that shows how to BF properly, as well as La Leche League. (Those websites are a great resource, and Medela has a lactation consultant who e-mailed me back in less than 24 hours!)
Also, sleep n play outfits for baby. (They look like footed pjs.) They will keep the baby warm, and it won't have to be swaddled or wrapped up in a blanket all the time.
Our swing! He loves it! (Conner is 2 weeks old tomorrow.) He hates his bassinet because he has too much room to move, and the swing makes him feel cozy and cuddled, even if it's not moving. We have the papasan swing.
We have the Diaper Champ. Love it! It doesn't take special bags like the Diaper Genie does, and has done a great job keeping smells down. We have 2 dogs who get into the trash constantly, and they haven't even noticed the Diaper Champ.
