My dog likes the Sophie more than my daughter I think! My wife and I bought a SNOO and it was pretty amazing. Very expensive, but my daughter has been sleeping through the night since we put her in her crib and she learned to self soothe there as well. Stay away from the rock n play as there were some infant deaths and they got pulled from the market. Many people will rave about them(our daughter used it and it worked well), but it is apparently not safe. I second the Dr. Brown bottles to limit the air bubbles. Youd be shocked how much it helps reduce the spit ups. I reccomend Amazon Prime as it's nice if you realize you need something but dont have it. It also has the deals on it and diapers and wipes pop up. I would not buy formula from Amazon if you go that route as some people have claimed people have messed with it...or something.
