NUK Woodlands Baby Bottle with Perfect Fit Nipple, 5 oz, 3-Count , Medium Flow, Boy Design

Nuk Orthodontic Bottles 0+m. The Nuk Orthodontic system is a line of products with coordinating designs and interchangeable parts that promote healthy oral development as your baby grows. These nipples have a superior design versus standard round nipples. The nipple is shaped like mom's breast during breastfeeding. It supports switching between breast and bottle. The Nuk air system vents the bottle, preventing vacuum build up - this allows baby to drink continuously, swallowing liquid instead of air.
