Mom's nipple has multiple pores.
Shouldn't your bottle's nipple?

Mother Nature	Second Nature

The Second Nature Nipple — a unique nipple that truly works like Mom's breast.

As baby latches on and suckles, the membrane flexes, the holes open up allowing more milk to flow. The "harder" baby suckles the faster the flow

The Second Nature Nipple offers many benefits:

Lets baby control the flow...
The Second Nature Nipple looks different from other nipples, because it is designed to be more like Mom’s breast, with multiple small holes for the milk to flow through. When your baby latches on and suckles on a Second Nature Nipple, it flexes and opens up the many small holes, which allows milk to flow. The stronger your baby suckles, the more the milk flow increases, so that your baby controls the flow just like at the breast!

Reduces swallowed air and colic...
When your baby is breastfeeding, she frequently pauses to rest. The Second Nature Nipple is the only nipple that effectively allows your baby to do the same thing while feeding from a bottle. When your baby stops suckling the holes close and immediately the flow stops, allowing your baby as much time as she needs before starting the flow again by suckling, just like at the breast! The free-flow nipples of other bottles continue to flow, forcing your baby to simply keep swallowing to avoid choking. Too much too fast overwhelms your baby’s sensitive digestive system and can cause colic. Second Nature’s natural venting further reduces gas and colic by preventing your baby from swallowing excess air.

Helps avoid nipple confusion...
Nipple confusion refers to the frustration that occurs when your baby, after having been bottle fed, does not want to return to the breast because she prefers the easy free-flow of other conventional bottles. However, with the Second Nature Nipple, your baby has to work the same way as when she is breastfeeding. This allows your baby to easily switch between the breast and the Second Nature Nipple. Therefore, nipple confusion is not an issue for the Second Nature baby!

There is no need for different flow rate nipples as baby grows — use the Second Nature Nipple from birth to 12 months.

In addition to the Second Nature Nipple, Second Nature offers a Cereal Nipple for thicker feedings and a Preemie Nipple for premature infants. Download our Nipple Flow Chart to help you decide which nipple best suits your baby's needs.
