Thanks to ALL of you for your input about my concern over my client's menstrual period returning! Answers came pouring into me from all parts of the world. You all have been a true blessing to me. It is a comfort to know you are out there. Most of the clients I see don't even realize lactational amennorhea exists! You should see their reactions when I inform them of this benefit if they "exclusively breastfeed"! Karen Christopher, LS Brookhaven, MS
