do something wrong. Just do what you think is best at the moment. You'll be fine.
My favorite was the whole "you're going to give your baby nipple confusion" if you want to breast feed but give her a bottle. You would think breast feeding is natural but it's anything but for most women. We were starving our daughter because we were afraid to give her a bottle of formula thinking she would never breast feed. Turns out she didn't care.... just wanted to eat.
