New Natural Response nipples are designed to work like a breast, with a unique drinking valve to mimic the way baby naturally drinks at the breast — with the same wide, breast-like shape and soft texture of our original Natural nipples.
If your baby is used to original Natural nipples, we suggest going directly to a higher numbered nipple from the new Natural Response range. See our chart in the image gallery for guidance.
Every baby has their own rhythm. Does yours seem frustrated, fall asleep during feeds, or play with the nipple? Try a higher flow. Do you see milk leaking from your baby's mouth, or are they gulping the milk down? Try a lower flow.
