Question about the SNS

[@llli*gentlemother]

My daughter has been using the SNS with one of her twins since a few days after birth. The babies are now 2 1/2 weeks old and the SNS baby is emptying less and less of the SNS. She won't nurse long if it isn't there, but when she's done there will only be 5-10 cc gone from it.
Is she able to nurse effectively from the breast and NOT empty the SNS? I guess I am not familiar enough with how that all works?

Thanks!

If her diaper output is adequate, it is quite possible that she is feeding predominantly from the breast and less and less from the SNS. That would be great! Some moms who use the SNS have the opposite experience.
