Why is caffeine a concern during pregnancy?
A small amount of caffeine is fine. However, if you have a lot of caffeine it increases your risk of having a baby with low birth weight, and increases your risk of having a miscarriage. The increased risk is small. But, it is best to play safe. The Food Standards Agency recommends that you do not have more than 200 mg caffeine in any one day if you are pregnant, or if you are trying to become pregnant.
