So anyway, we've been keeping this in mind and wondering how soon we can start trying again. My body, aka the baby factory, decided that I was ready to concieve again a mere 2 months after Mira was born. (Much to my dismay. I mean couldn't I even get a good 6-months in before my cycles started up again?!?! Yes I did just say that in front of the entire web.) The main thing is that my OB has told me that I shouldn't get pregnant again too soon because there is a significant risk that I will lose my milk. And if that happens while Mira still needs to be nursing, then we'd have to start her on formula, which I'd really rather not do (formula is expensive). But then again, I've met plenty of moms who have nursed through pregnancy. I've even met one who is going to be nursing her nearly-two-year-old and her soon-to-be-born baby simultaneously (a practice they call "tandem nursing"... who knew?).
In the end, we think we're going to start trying for baby #2 around November. Mira will be around 10 months then, and could probably get by on solids if needed. Also, by the time the next baby is born Mira would be around 20 months, old enough to potentially be potty trained and to be out of her crib. On the down side, that does mean that I'll be big and pregnant and chasing a toddler in the heat of the summer, but with a little AC and plenty of water, I think I can manage.
So that's the plan. We'll see if things go accordingly.
