Breastfed babies don't only take their milk from the breast. While lactation consultants suggest waiting at least three weeks before introducing a bottle, breastfeeding mamas often abide by their own schedules. Finding a bottle that truly mimics the motion, flow, and feeling of the breast is often the hardest part of making the switch. We've put countless bottles to the test, and narrowed our list down to nine. Check out our picks for the most breast-like bottles on the market, and let us know which one you (or your children) prefer.
