What do you worry about?
I was never one of those green-tea-swilling, pineapple-munching, my-body-is-a-temple TTCers. I mean, it probably didn't hurt that by the time I started TTC, I'd already spent my 20s transitioning over into a diet of less meat, more beans/greens/grains, organic/hormone-free when I could, no high-mercury seafood, etc.; that I've never been a big caffeine consumer or fast-food addict; or that I'm smoke-free and, thanks to local ordinances, almost never come into contact with cigarette smoke anywhere in my daily life. But I drank (copiously) during my follicular phase, consumed refined sugars with abandon (except when metformin punished me for it), ate street food in Bangkok and slathered myself with DEET in Cambodia.
Once I got pregnant, it was a mixed bag. I ate as decently as I could, but several months went by when I couldn't force down a green vegetable if my life depended on it, and once freed of the bowel-churning grip of metformin, I never met a brownie I couldn't love. I've avoided the litter box (but really, when you have a totally indoor cat, pregnancy is just a convenient excuse to avoid a stinky task), but have had no problem eating slightly rare meat, smoked fish, soft cheeses (though I do steer clear of raw milk cheese), or cold cuts. Hey, when you are seven months pregnant and craving a muffaletta, nothing else will do. My doctor said sushi was fine, and if I'd been more mobile during this pregnancy, I would have eaten it nonstop. (Unfortunately, the only sushi place that delivers in my 'hood is slightly sketchy, and I'm thinking if I eat sushi, it should at least be good sushi.) I got a thimerosal-containing flu shot and haven't looked back. I have mostly avoided alcohol--just a few thimblefuls of wine through this whole pregnancy--but haven't been particularly militant about it. My husband makes the most divine sauces using wine or brandy and I'm not going to obsess over whether every particle of alcohol has cooked off (which I'm sure it hasn't).
Instead, I've gotten swept up in more obscure worries. (Incidentally, you know you have gone off the deep end when you identify with a parenting subculture written about in New York magazine, home of the repulsively overprivileged with too much time on their hands.) Phthalates, PDBEs, parabens in my personal care products, and of course the Dresser of Death. I've bought "green" cleaning products, an organic crib mattress, and glass baby bottles. In other words, I've basically ignored the things 99.999% of pregnant women worry about and zeroed in, laser-like, on the things only 0.001% of humans have even heard of.
(I am NOT, however, worried about the effects of ultrasound, as was a recent poster on the mothering.com message boards who was freaking out over having had three ultrasounds her whole pregnancy and would it give her baby autism. Having had probably 20+ ultrasounds this pregnancy, I could only laugh.)
The scariest part is, as Meira so eloquently pointed out in her comment to my last post (and BTW thank you, Meira, for saying EXACTLY what I needed to hear, both about the breakdowns and about the breastfeeding), and as someone said in the comments to Jo's post, even if we do everything "perfectly," there are no guarantees. You can have the purest diet, the healthiest lifestyle, the cleanest environment around, and have cycle after cycle after cycle crash and burn, or suffer multiple losses, or have a child with serious problems. You can eat nothing but McD0nald's for nine months and have a happy, healthy baby.
