Hello, I am a hospital based Lactation Consultant. I would like to get more information about why the starter sns needs to be discarded after only 24 hours. I would like to use these for inpatient breastfeeding mothers who need to supplement, but it is hard to justify finances if it is only good for 24 hours. I would suggest a starter product like this should be manufactured to be able to be used for at least 7 days, at the very minimum, at least 4-5 days since C-section mothers stay in hospital for that length. If I started a C-section mother on this system, I would need to use 3-4 of these kits just for the time she is in the hospital. For a vaginal mother, it could be 2 kits. I think mothers need some time to see if this supplementing at the breast system works for them before they commit to making the purchase of the SNS itself. I know I've read about this issue on Lactnet as well. I have called Medela in the past and I was given the 24 hour time frame due to the 'type of plastic' it is made from. I would really appreciate more info.
