Wow! Thanks so much, everyone, for your replies so far!
I think in most ways I am in the middle. I try to remind myself that with my pregnancy with DD, I was not nearly as awesome or aware. I ate a ton of McDonalds crunchy ranch snack wraps (the poor thing) and Fruit Roll Ups, and I don't remember being overly conscious of avoiding chemicals or anything like that. (I was also 16/17.) That said, I was a vibrant, glowing, healthy as hell pregnant woman who used to get stopped by strangers to be told so, and though I gained a fair amount of weight (40 pounds or so) I had zero health issues, and had a totally natural complication free delivery, went on to BF exclusively, recovered without any issue at all, and lost 50 pounds within four or five months.
This time around, I am supposedly 'healthier', but less so in other ways. I eat organic whenever I can, get a large portion of our produce locally, eat a TON of fruits and veggies (they dominate my diet), whole grains when I eat grains, local pastured eggs, high quality cheeses when I eat cheese, organic dried fruits, etc etc. I drink a ton of water and keep coffee to a minimum, and rarely if ever drink anything else aside from the occassional glass of organic milk or almond milk. I do have some difficulty keeping my portions small when we eat out, get pizza, have bday cake, whatever- but overall I eat mainly homecooked goodness. We never get fast food, rarely get anything very junky (if I'm going to eat junk, I find organic/natural versions of it.)
However, I am much more aware of weight gain this time, and I think if anything this is a negative, since it causes some stress. I definitely don't have that "I'm pregnant, I can eat for two!" mentality, mainly because I'm worried about getting it off after, especially with this baby born right at swimsuit season. I know in my mind this shouldn't be a real concern, especially since I began at a totally healthy 'normal' weight (although higher than my ideal), but weight has been a mental preoccupation of mine for a couple years now, and although pregnancy might soothe it, I don't see me forgetting it anytime soon.
As far as other stuff goes, I'm fair to middling :) I use Dr Bronners, and just switched to an organic conditioner, and if I use lotion it's an organic brand or coconut oil. I use non flouride Toms toothpaste, and have avoided hair color, though I'm considering some foils to brighten up my brown around the holidays. I don't use makeup every day, but when I do, it's totally not organic :/ I use my cellphone too much, and my laptop, and just got an IPod touch, so that's not very good, I suppose ... and I take a very clean prenatal, etc etc.
I worry about caffeine intake, since I'm sensitive to it ... and I worry about the cell and wifi exposure, but feel powerless to change it.
I don't freak out over too much, really, and I feel like I'm doing alright; my blood work from the first trimester came back excellent in all regards, though I feel not as shiny and brilliant at all as my first pregnancy. I chalk this up to the residual exhaustion of being a parent of a very vivacious four year old. My mental state is not as cheery; I'm more jaded and tend to stress more about how I'm going to pull it all off (well) than I did with DD, who I just happily 'knew' I'd do well with.
Right now I'm switching over to mainly vegan/ 50% -ish raw diet, so maybe some of this exhaustion is from that ... and I've reached the "I can't get comfy" sleeping stage, which I ABHOR.
