It's safe to have 200mg of caffeine a day. Equals about 1 cup of coffee/soda. It's best to drink water when prego. Also remember caffeine is found in many things other than a cup of coffee. It's in soda, tea, chocolate, some candy etc. just pay attention. You didn't do any harm to Ur baby drinking Ur soda one day. Try to drink regular OJ, juice & water, with juice be careful if you drink too much w high sugar you'll just pack on the lbs.
