Air-Free Feeding: Boon's Nursh baby bottles feature a unique silicone pouch which collapses as baby drinks without complicated straws, valves, or vents
Swap the Top: These Boon Nursh sippy cup lids are designed to fit perfectly onto your Nursh bottle shells, so you'll have an instant array of colorful sippy cups for your little one to choose from
Safety of Silicone: Each of these 4-ounce newborn bottles are designed with 100% silicone pouches so milk never touches plastic during baby's mealtimes
Easy Transition: Attaching this sippy cup lid to your little one's baby bottle helps ease the transition from bottle to sippy cup by using the bottle shell your child is already used to
That Natural Feeling: When it needs to feel real, it has to mimic nature. The slow flow nipples are easy for baby to latch on to and encourage proper tongue positioning
