It can also be used for infants who cannot maintain vacuum long enough.

Medela’s Supplemental Nursing System (SNS) is a reusable device which is suitable for both repeated daily use for a duration of 3 months.

Consult your Healthcare Professional for further information on how long to supplement for and when to transition or wean off using the SNS.

The Medela Supplemental Nursing System (SNS) is specifically designed to be easy to use. After the SNS is cleaned, assembled (with the flow stop engaged) and filled with the required amount of milk, clip the device securely to a bra strap, top or pillow. Position the baby at the breast / chest. Once a good latch is established, gently insert the thin, flexible tube 1.5-2cm into the top corner of the baby's mouth alongside the nipple. Open the flow clamp to let the milk flow. With the help of gravity and the advanced venting system, a controlled and consistent flow of milk is released to the baby as they feed.

For further information on how to use the SNS, please read our Instructions for Use, as well as the SNS How To Video, and SNS Quick Card.

The Supplemental Nursing System (SNS) can be easily cleaned at home. Before first use and after each use, clean all the components in plenty of warm soapy water, then rinse with clean water and dry with a clean cloth or leave to dry on a clean cloth. Use the specialty Cleaning Aid to effectively and easily clean the tube by flushing it with warm, soapy water (3 times), then clean water (3 times), and finally with air until its visibly dry. Then, further clean the Container, TwistLok Lid, Valve and Lid components before first use and once daily in boiling water for 5 minutes, in a dishwasher or in the microwave using Medela's Quick Clean bags.
