If caffeine effects you, it effects the baby and even if you don't feel it its effecting the baby. Caffeine does cross to the baby, you can drink it anyway, but you can't say it won't have an effect since that's not what research shows. Maybe the effect doesn't bother you though. I know lots of women who say they had to stop drinking caffeine when breastfeeding because of all the crying their babies would do hours later. I drank caffeine when I was pregnant with David, and he's okay (I would drink caffeine at my job

), I am not saying its going to cause something terrible to happen, but there will be an effect.
Everything we eat or drink has an effect on our health, pregnant or not. Since I am passing my eating and drinking habits to David I am always trying to improve them by eating lots of veggies and whole grains-- not to mention I would like to be a healthy old lady.

Ideally I hope to not drink pop at all, which is what I have been doing, but if I absolutely must have it then I will drink Sprite since at least it is caffeine free.
I don't know, considering that 66% of America is officially obese, I think the least we can do is cut out empty calories and yucky drugs like caffeine. But I realize that 66% of America, at the very least, doesn't think so. Oh well, I only have to care for my family so that's what I'll stick to and I'll do the very best job that I can.
