As long as ur not going over 200 mg per day ur fine. Im a mommy of 3 and always have been a Dr. Pepper drinker with all 3. They all are healthy and born on time at very healthy weights.
Try switching to carbonated water or ginger ale since its caffeine free!
Yes caffine goes straight to your baby. I think you can have 200mg of caffeine which is equal to 8oz of coffee (smaller than a Starbucks tall cup) I'm not sure how much is in a can of soda because I'm more of a coffee drinker but if your drinking more than one can it can be harmful.
