We're on a break from TTC'ing after a miscarriage last month (I was 9 weeks along, ugh it still makes me so sad to say that). Anyway, DS is 28 months and we're still breastfeeding, about 2-3x times a day, typically in the early AM and to go to sleep at night, and occasionally when we reunite after being apart because of work/daycare (oh, and on the weekends maybe 1-2 times more, before naps).
Our hope is to start TTC again in a couple of months, and in the meantime try to wean DS very gradually and very gently, though I'm not willing to push it if he seems upset by it.
My motivation for weaning is manifold, but also ambivalent; I so wanted to do child-led weaning, and I know DS gets so much comfort and closeness from it (as do I!), particularly since I work full-time now and we're separated for such long stretches during the day. But I also sense he's at a good point for a gradual weaning, and I also have an intuitive sense that I need to wean fully in order to maintain a pregnancy. I try not to "blame" the breastfeeding for the miscarriage, and deep down I don't -- it's more that my gut is telling me it will best to have as few sources of worry as possible, and if I'm breastfeeding I'll worry about it, particularly since I know this next pregnancy will be filled with anxiety now.
That said, I'm willing to face those fears if the weaning doesn't "take"; if DS seems to still need nursing, I'm unwilling to push it. We'll just try again, and cross our fingers.
In the meantime, I'm cheering for all of you -- I love seeing breastfeeding moms able to get preggers and bear healthy babies! It can happen, it can happen!
