Exercise During Pregnancy
There are two main reasons for concern about exercising during pregnancy. One is that it may reduce the baby's oxygen supply, since exercise, like other sources of stress, reduces blood flow to the uterus. Another risk is overheating. As we have already seen, fetal development is highly sensitive to temperature, and elevations of more than 2^0 C (or above 1020F) can increase the risk of miscarriage and affect the formation of the brain and eyes.
Despite these theoretical concerns, there is ...There are some concerns about the mother exercising during pregnancy, but the benefits appear to outweight the potential deleterious effects and have no apparent effect on the child's IQ.

The Importance of Nutrition in the Developing Mind
In the case of a mother's more general nutritional status—her tota caloric intake—the brain is actually less sensitive during the first three to four months of gestation. In spite of its massive developmental changes, the fetus grows surprisingly little in size during this period, so its growth is not very dependent on the mother's diet. (This is probably no accident, since women are often unable to consume many calories because of first-trimester nausea.) Beginning around midway through ...There is a crucial period in fetal development where nutrition is of the utmost importance to the growing brain. If these nutritional needs are not met, then the baby's intelligence may suffer.

Effects of Caffeine on the Developing Fetus
Caffeine crosses the placenta and may even concentrate in the fetal circulation. Concern about its effect on fetal development stems from animal studies, where it has been found to be teratogenic when fed to pregnant rats in high doses; a dose equivalent to 150 cups of strong coffee per day causes malformations in rodents such as missing limbs and digits. However, caffeine does not appear to be a teratogen in h humans. The average pregnant woman is estimated to consume 144 milligrams per day ...Moderate consumption of Caffeine appears to have no impact on a child's IQ; however, massive consumption causes deformities in rats.
