After some research, we conceived the Second Nature bottle to assist Mother Nature. This bottle functions similarly to mother's breast in order to effectively supplement breastfeeding. Proper suckling action is required by infants to extract milk during breastfeeding. This suckling action occurs when baby latches to the areola portion of the breast past the nipple. The gums compress the milk sinuses, and the tongue is located over the lower gum, its motion stripping the milk. The baby sucks the areola, not the nipple, to gather the milk from the pores. When baby needs a rest, suckling stops and milk no longer flows. Before Second Nature, all bottles were designed with a hole at the end of the nipple that was always open. This allowed milk to flow whether baby was trying to extract milk or not. In these bottles, the milk flowed without any suckling action, all baby was required to do was swallow. Proper latching and suckling were no longer required to gather the milk and the suckling dynamics of the pallet changed. If the milk flowed too fast or baby needed to rest, the tongue rolled back to try and cover the open hole. At this point, the baby was drinking as though the bottle were a straw. If the baby could not keep up with the flow, milk spilled out the sides of baby’s mouth. Once baby became used to continuous flow bottles, returning to the breast was difficult.
