During pregnancy caffeine can pass to the baby via the placenta as with most of the things you ingest on a daily basis. For this reason there are limitations on the amount of coffee a pregnant woman should drink. This currently sits at around 300mg per day. But let’s consider it in a bit more depth.


In pregnancy caffeine ingestion can result in your baby being ‘smaller’ for its age and increasing the gestational period of your pregnancy. Researchers found that 100mg of coffee could increase a woman’s gestational period by around 8 hours. As babies who are small for their gestational age can experience a lot of health complications, its considered that the daily intake limit needs to be re-evaluated.

Another study in London found that in women in the midst of pregnancy caffeine consumption that was above average could lead to the chance of having a miscarriage doubling. Coffee presented more of a risk than other caffeinated beverages such as cola or tea, due to the concentration of caffeine content in the former. Accordingly coffee presents a large risk to unborn babies.

Beyond the effects on the foetus, we must also appreciate that during pregnancy caffeine consumption to excess can result in heart palpitations, high blood pressure and restlessness. These are undesirable in an expecting mother. Experiencing these side effects will affect the mother’s quality of life and in turn the development of the baby.

Knowing what has been suggested by these studies, one would imagine a complete caffeine break is the best way to approach your pregnancy. If anything, while pregnant caffeine should be put on hold for nine months will help you sleep better and perhaps break a bad habit. In any case, the break will be temporary, so if you are a coffee addict, you only need hold out until the baby is safely born.
