We still have the support of an LC, and she said that she has had several clients use the sns and decide it's not for them. Apparently there's very little solid research into the touted supply building properties of it. We used the Medela one. In fact, we were lucky enough the the LC gave it to us for free, as Medela fund a lot of the research done by her university based human lactation research group. I've seen on forums that the US one - Lactaid - is 'better' for some people, at least, but I don't think I'll try it because I'd still have to use the tape, and my skin just doesn't handle it very well.

I think if you feel distinctly less full after a feed she must be getting a good amount from you. One thing my LC mentioned is that you can get everything in place but not unlock the tube on the side she's feeding on for the first little while, and when the rate of swallows drops down to one every 9 or 10 sucks, instead of every 2 or 3 sucks, then released the tube so she then gets the milk from the bottle. When she's half way through the bottle, change sides and do the same thing on the second side. That way you know she's getting as much as she can from the breast as well as the top-up.
