Does caffeine hurt a baby while you are pregnant?

Yes. Caffeine can lead to developmental problems of the baby. It is recommended that you drink no more than two cups of coffee per day while pregnant. None at all if you can manage it. Remember that caffeine is present in coffee, black tea, green tea, some soft drinks, cocoa and chocolate. So having tea instead of coffee is not a good alternative. Decaf coffee is also bad for the baby. Do not drink more than two cups per day.
