I am pregnant with my third, and I was unable to breastfeed my first two. Since then, I discovered that I have insufficient glandular tissue, so breastfeeding alone is most likely not in the cards for me. My question is, I want to try using a SNS, but I don't know which one to purchase. I have heard that the Lact-Aid is better, and that it forces the baby to suck more, but some people swear by the Medela. Has anyone used one of these, and if so, what did you think?
