You won't know until you meet your precious little one which type of nipple they'll prefer to use (assuming you'll be bottlefeeding at some point), so the Babylist Bottle Box ($25, originally $44) is a great place to start. Rather than having to dart out in the middle of the night to purchase a new brand of bottle, this kit has all of the major heavy-hitters included: Dr. Brown's, Comotomo, Philips AVENT, Tommee Tippee, and Munchkin.
