Give mom the most perfect gift, the NUK Simply Natural Bottles Gift Set. This 9-piece set has what she’ll need to naturally bottle feed and soothe her baby and features subtle colors and premium designs to fit your baby’s personality. NUK Simply Natural bottles are simply the best way to combine breast and bottle, because they’re designed to be closest to mom’s breast. Unlike most bottles, they have multiple nipple holes to mimic the flow of milk from mom, and our bottles feature an even softer nipple than before. The advanced 1-piece Anti-Colic Air system helps reduce colic, gas and spit up. Color: Girl. Gender: female.
