I'm interested to hear about other people's experience with using a Supplementary Nursing System (SNS).
We started using the SNS feed line last week and its going well.
DD gets her ebm or formula in in thin silicone tube attached to my nipple so she gets breastmilk and the suppliment as she breastfeeds.

If you've used a sns, how many did you have?
What did you like/ dislike about it?
