Product Usage

  • What can be fed through the SNS?
    • Breastmilk is the preferred nutrition for babies. Clinicians may recommend other fluids, fortifiers and/or medications to meet the baby's medical and nutritional needs.

  • How do I start the flow of the SNS?
    • The system can be primed by squeezing feed from the container into the tubing. Release only one side of the tubing at a time from the attachment ring when feeding the baby. Gently tickle the babies lip with the nipple and tube.

  • What is the proper positioning for the SNS?
    • The tubing should extend about a ¼" beyond the nipple. The tube should be in the center of the upper lip of the baby and not off to the sides. Reposition the baby if there is no flow. Reposition the tubing if there is no flow. Make sure the tubing is not crimped.

  • How do I adjust the flow rate of the SNS?
    • The easiest way to change the flow is using the different sizes of tubing. The small tubing has a red valve, the medium has a white valve, and the large has a clear valve. The flow can also be adjusted by the height the system is worn. When the bottom of the SNS container is above the level of the nipple, the feed will flow more quickly. When the SNS is placed below the level of the nipple, the feed will flow slowly. The flow can be increased by gently squeezing the SNS container while the baby is feeding. Warming the feed can increase the flow.

  • When do you use an SNS?
    • The SNS was developed to allow the baby that is not getting enough nourishment at the breast to receive extra feed or supplements while remaining at the breast. Adoptive mothers often use the product to help re-lactate or for the bonding experience the system can provide between mother and baby. The SNS should be used on the recommendation of a lactation consultant or physician.
