My brest friend is the only pillow that stays securely in place and does not shift or slide like other crescent shaped pillows. It provides support, comfort and security to both mom and baby, making breastfeeding more enjoyable and successful. The deluxe slipcover is made of extra soft, plush fabric and is great to have on hand when one is in the wash. Many moms enjoy buying extra slipcovers so that when spit up or leaky diapers strike, they can toss the slipcover into the washer without missing a beat.
