How does caffeine affect pregnancy in the third trimester?
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. Quick answer: The 2 hour coffee rule suggests waiting at least two hours after waking up before drinking your first cup of coffee. This guideline aligns with the body’s cortisol levels, aiming to optimize both the effects of caffeine and the body’s natural wakefulness cycle.According to the FDA, the half-life of caffeine — the time it takes for the starting amount of the substance to reduce by half — is between four and six hours. This means that up to six hours after drinking a caffeinated beverage, half of the caffeine you consumed is still present in your body — keeping you alert.During pregnancy, caffeine half-life remains the same during the first trimester but increases to 10 hours at 17 weeks gestation (38). By the end of pregnancy the half-life in non-smokers varies from 11.With so many factors impacting the rate at which caffeine is cleared from the body, it is difficult to say exactly how long caffeine lasts in a person’s system.

CI] 1.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].Babies of pregnant women who consume over 200 mg of caffeine per day are at an increased risk of fetal growth restriction which could result in low birth weight and/or miscarriage. There is evidence that excessive caffeine intake is associated with an increased risk of miscarriage.Due to conflicting conclusions from numerous studies, the March of Dimes states that until the results of more conclusive studies are available, pregnant women should limit caffeine intake to less than 200 mg per day. This is the equivalent of about one 12 oz cup of coffee.It increases fetal breathing and heart rates but can lead to reduced growth and a lower birth weight. Although it does not affect gestational length or cause hypertension, caffeine increases uterine contractions, potentially resulting in spontaneous abortion.

How do I know if my baby is affected by caffeine?
Increased heart rate and blood pressure: caffeine is a stimulant; infants may show tachycardia and transient hypertension. Agitation and irritability: crying, inconsolability, increased motor activity. Sleep disturbance: difficulty falling asleep, frequent wakings, shorter total sleep. Most babies tend to be more active in the evening hours. This can start as early as the second trimester. A baby may be more active about an hour after the mother eats. This is because of the increase in sugar (glucose) in the mother’s blood.You may feel your baby move more after you eat, or after you drink caffeine.

Therefore, caffeine intoxication in pregnant women should be treated immediately.Researchers have not reported an association between low (under 200 mg) levels of caffeine and an increased chance of miscarriage. Some studies suggest that the chance of miscarriage might be increased when people consume moderate (200-300 mg) or high (more than 300 mg) levels of caffeine.For preeclampsia, the results of subgroup analyses comparing caffeine exposure with noncaffeine exposure revealed that coffee and soft drink intake during pregnancy may increase the risk of preeclampsia, although there were only two studies in each subgroup analysis.
