I'm interested in responses too as we would like to start ttc #2 as soon as possible and would like to be ready when #1 is around 6 months but I don't want to stop BF'ing #1 either. Apparently acupuncture is great for getting your cycle back on track as it's your hormones that will determine whether you ovulate and whether you get AF which is also why you can ovulate without getting AF and you can get AF without ovulating... so yeah that is what I will be doing to get my hormones balanced as soon as possible after the birth so that I am hopefully ready down stairs to conceive when the time comes.
