Hi! Just wanted to give a quick update
My baby was born on March 30th and fortunately we have been doing well with the bf. The shells did help draw out my nipples some, although I don't use them anymore now. Too much leaking after my milk came in. Besides, since he has a good suck, he draws them out.
Now, 10 days later, I've developed some cracks - not too bad (at least yet). I'm using lanolin to heal them. However I'll put that in a different post.
Thanks again for all the suggestions on flat nipples!
