Description of Medela Supplemental Nursing System

The Supplemental Nursing System is an ideal way to administer supplemental nutrition to babies while they are being breastfed. The system supports the unique bonding between mum and baby, motivating both of them to keep moving towards a more satisfying breastfeeding experience. This can be achieved by allowing the baby to get any additional milk they require through the SNS while feeding at the breast.

The SNS is intended to enable mums to breastfeed when they would otherwise be unable to do so, and help the baby train their sucking behaviour. It offers the following advantages:

  • It can be used by mums who have or think they have a low milk supply
  • It helps to stimulate the mum’s milk supply through direct sucking at the breast
  • It can be used when there is a requirement for supplements in addition to breast milk
  • It trains the baby to suck properly by creating a vacuum at the breast

The Supplemental Nursing System is a reservoir that is filled with supplemental nutrition. It can then be placed on the mum’s chest or on a pole. The very thin, flexible tubes are fixed alongside the mother’s nipples and release additional milk and supplements as the baby feeds.


  • Designed for weak or premature babies, for infant training, to stimulate the breast milk, to feed adopted baby's with breast milk or to feed for a long time.
  • Adjustable power system, for different feed rates     
  • Bottle with gradation, to control the amount of milk     
  • The system is designed to have the same position as breastfeeding

Use of Medela Supplemental Nursing System

Preparing for feeding
  1. The SNS is supplied with three sizes of tubing. When you use the SNS system for the first time, start with the medium (white) valve.
  2. Place the silicone valve holder onto the valve.
  3. Slide the tubing with the valve on top through the attachment ring. Push the valve in until it snaps into place.
  4. Fix the neck cord on the bottle: Pull the cord with its soft ending (without the clip) through the hole in the bottom of the bottle. Pull the ending with the metallic clip through the cord loop you created in the previous step. Pul firmly.
  5. Fill the bottle with the supplemental nutrition which you prepared and heated in a separate
    container. Screw the attachment ring with the valve and tubing onto the bottle. Squeeze the
    bottle gently, so that the milk flows through the tubing.
  6. Lock both parts of the tubing in the slits of the attachment ring. Place the SNS system around your neck with the tubing hanging down.
  7. Check that the bottle shoulder is at nipple level. To raise the bottle, unlock the lock of the cord and move the entire lock downwards. To lower the bottle, move the (unlocked) lock upwards. When the bottle is in the right position, fix the lock.
  8. Cut off a piece of tape of approx. 6 cm. Place the tube onto the breast such that it protrudes
    from the nipple by 1 cm. Repeat this step for the other tube and the other breast.
  1. Hold your baby close to your breast. To encourage your baby to open its mouth, tickle its lower lip with your nipple. Leave a tiny space between the nipple and your baby’s mouth.
  2. Wait until your baby opens its mouth wide, then put your baby onto your breast. Only when the baby’s mouth is wide open, allow it to latch-on.
  3. Check that the tube position in the baby’s mouth is correct: the tube should enter the mouth in the middle of the upper lip or at the corner.
  4. Once you and your baby have found the right position, let your baby breastfeed. When your baby starts suckling, release the tube from the slit in the attachment ring. The milk in the SNS bottle can now flow through the tube. Continue breastfeeding.
  5. If the milk does not flow well, also release the second tube. Attach the tube with the opening upwards to your body, on a level with the bottle bottom.

    I thought it worked well, occasionally would leak milk but that was normally because I hadn't put it together correctly. I would use again if I needed too

    I used the Medela SNS for approx 2 Weeks with great success. It enabled me to breastfeed my newborn baby who's got problems with her tongue causing us enormous breastfeeding problems. I found it a little bit fiddly, but I had no trouble working it out and we did a lot of successful feeding. However after about 2 Weeks three SNS started leaking and us now unusable.

    Very useful! I am very pleased with this sistem, it helped me to increase my milk supply within 2-3 weeks because my little man was getting angry on the breast because the flow was slow- with this sistem he sucked longer and lactation increased. And my little one has reflux and I am able to mix the medicine and to give it to him while eating on the breast without using the bottle anymore to confuse him ! It is a little harder to get used to use it but very quick you get into routine! I don't score 5 because it doesn't have a system to refill the bottle from top while feeding! But it worth all the money !
