Some moms struggle with figuring out what amount, if any, of caffeine is safe during pregnancy. Because caffeine can increase blood pressure and heart rate, this may be an issue for the fetus. The World Health Organization recommends limiting caffeine because of increased risks of having a low weight baby and increased pregnancy loss. The American College of Obstetricians and Gynecologists come down on the side of saying that keeping coffee intake to about 8 ounces per day “doesn’t appear to be” a risk factor in regards to miscarriage or preterm birth.
But, if you are like me, your caffeine does not come only in the form of coffee; it comes from other foods like tea, chocolate or soda. So, if you are concerned about what amount of caffeine is safe for you, talk to your medical provider and find other ways to get that energy boost throughout your day. At least for these nine months.
