Overall conclusions include that there is insufficient evidence of a causal association between caffeine use and increase in spontaneous abortions, particularly if less than 300 mg/d is consumed; there is no increased risk of birth defects; and there are insignificant reductions in fetal growth with caffeine ...
Caffeine has not been shown to cause an increased chance for birth defects above the background risk.
Previous studies have found caffeine can have a negative effect on pregnancy. It is also known that a fetus does not have the enzyme necessary to breakdown caffeine when it crosses the placenta. This new study reveals that caffeine could also leave a lasting impact on neurodevelopment.
Caffeine may cause you to feel jittery, have indigestion or have trouble sleeping. During pregnancy, you may be especially sensitive to caffeine because it may take you longer to clear it from your body than if you weren't pregnant. It may also make you feel nauseous or lightheaded.
(A) In humans, caffeine intake during pregnancy may give rise to pregnancy complications, such as miscarriage [4,17], fetal growth restriction [5,12], and low birth weight [21–24], which would also increase the risk of overweight and impaired cognitive development in childhood [25–27].
Our findings suggest gestational caffeine intake may represent a marker of vulnerability to childhood ASD-related behaviors. Additional studies are warranted to extend these findings.
The American College of Obstetricians and Gynecologists (ACOG) recommends that pregnant women limit their caffeine consumption to less than 200 mg (about two, six-ounce cups) per day.
Recommendations for pregnancy
The recommended limit in Australia is a maximum of 200mg caffeine per day. This would be equivalent to 1 cup of strong espresso style coffee, 3 cups of instant coffee, 4 cups of medium strength tea, 4 cups of cocoa or hot chocolate or 4 cans of cola.
Some reports suggest that children exposed to more than 500 mg of caffeine per day in the third trimester of pregnancy were more likely to have faster heart rates, shaking, increased breathing rate, and spend more time awake in the days following birth.
Yes. The Food Standards Agency recommends that pregnant women shouldn't take more than 200mg of caffeine a day. A can of Coca‑Cola Classic contains 32mg of caffeine and a can of Diet Coke contains 42mg.
Although caffeine does cross the placenta, it has been shown that caffeine does not cause a decrease in uterine blood flow or fetal oxygenation 8. Two studies have assessed the relationship between caffeine consumption and mean birth weight differences 6 7, and two others have recently reported on IUGR.
In a 6-month-old baby, the half-life of caffeine is around 2.5 hours, but for a newborn, it is a few days. Drinking caffeine may affect the nutritional quality of your breast milk. Mothers who drink three cups of coffee per day have about one-third less iron in their breast milk than mothers who don't drink any coffee.
“As beverages with caffeine are consumed frequently, controlling their intake may reduce a risk for nonoptimal cognitive development in children,” says Dr.
Caffeine and congenital malformations
One paper reported weak positive associations between maternal caffeine consumption and spina bifida (neural tube defects), but without a dose-effect relationship and with a negative association for tea.
“Anyone planning to have a baby needs to know that consuming caffeine during pregnancy can raise the risk of stillbirth and other pregnancy complications, so it's important to cut down as much as you can; the national guidelines should be the limit, not the goal, and the more you can cut down beyond that the better.
Key Takeaways. Consumption of caffeine during pregnancy could raise risks, both for a healthy pregnancy and for fetal development, a recent meta-analysis finds. The situation is particularly acute during the third trimester, since caffeine stays in the body longer due to maternal metabolism changes.
During pregnancy, all drinks with significant levels of caffeine such as coffee, cola and energy drinks should be avoided. It is best to switch to decaffeinated drinks or drinks without caffeine There is no known safe level of caffeine whilst you are pregnant.
Even a small amount of caffeine can cause changes in your baby's sleep pattern or normal movement pattern in the later stages of pregnancy. Remember, because caffeine is a stimulant, it can keep both you and your baby awake.

If you're still craving a warm cup of something once you've hit your caffeine limit, consider a caffeine-free tea, such as chamomile, ginger, or rooibos, to keep your morning ritual intact.
One area of continued research is the impact of caffeine during pregnancy. A recent study published in the International Journal of Epidemiology found that drinking coffee during pregnancy likely does not contribute to poor pregnancy outcomes such as pre-term birth, miscarriage, or stillbirth.
Caffeine is safe during pregnancy in moderation. The American College of Obstetricians and Gynecologists (ACOG) reports that it is safe to consume less than 200mg of caffeine per day, without any notable side effects for mom or baby.
Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father.
