Very Interesting Denise!
So I presume if you have twins and a low supply issue it would be better NOT
to tandem nurse in terms of maximizing milk synthesis?
Now, I have always practiced under the premise that dual fdng increases
prolactin, figuring that was the goal....... but this work suggests that
prolactin levels are relatively unimportant....hmmm...
