there is correlation between maternal caffeine consumption and its effects
some studies recommend coffee during pregnancy after 3 months and the other refuse to drink coffee at all. so i need consistent findings on intake of coffee and its effect during pregnancy
Pregnant women who down six coffee cups’ worth of caffeine every day may have smaller babies than those who consume less caffeine, a new study finds.

Coffee, but not caffeine, consumption was associated with marginally increased gestational length but not with spontaneous PTD risk. Caffeine intake was consistently associated with decreased BW and increased odds of SGA. The association was strengthened by concordant results for caffeine sources, time of survey and different SGA definitions. This might have clinical implications as even caffeine consumption below the recommended maximum (200 mg/day in the Nordic countries and USA, 300 mg/day according to the World Health Organization (WHO)) was associated with increased risk for SGA.

Thank you for asking this important question, actually coffee is advised to pregnant women but with a certain quantity as it may lead to low birth weight babies when in excess. open this link for more information: https://www.theguardian.com/lifeandstyle/2013/feb/25/is-coffee-dangerous-during-pregnancy
Caffeine intake has been studied with mix results. Most authors, along with the American College of Obstetricians & Gynecologists (ACOG) recommend limiting caffeine to 200 mcg (about 12 oz of brewed coffee) per day. This amount of caffeine has not been associated with adverse pregnancy, fetal, or neonatal outcomes. Consuming higher amounts of caffeine in pregnancy and during lactation is not recommended and has been associated with higher rates of spontaneous abortion, preterm birth, and intrauterine growth restriction. As a certified nurse midwife, I have advised women to avoid drinking more than 2 servings of caffeinated beverages per day.
Like Michele has said, studies on caffeine consumption during pregnancy give conflicting reports but most did not suggest any increase in adverse effects during pregnancy, especially when consumption is less than 300mg/day. However, it has been recommended that pregnant women limit consumption of caffeine to not more than 200mg/day. For now, data on consumption of more than 300mg/day are limited and conflicting probably due to methodological differences. More studies are therefore needed on the causal relationship between caffeine consumption and pregnancy. Some studies have already been suggested for reading. Thank you.

Abstract
BACKGROUND:
Clubfoot is associated with maternal cigarette smoking in several studies, but it is not clear if this association is confined to women who smoke throughout the at-risk period. Maternal alcohol and coffeedrinking have not been well studied in relation to clubfoot.
METHODS:
The present study used data from a population-based case-control study of clubfoot conducted in Massachusetts, New York, and North Carolina from 2007 to 2011. Mothers of 646 isolated clubfoot cases and 2037 controls were interviewed about pregnancy events and exposures, including the timing and frequency of cigarette smoking, alcohol intake, and coffee drinking.
RESULTS:
More mothers of cases than controls reported smoking during early pregnancy (28.9% vs. 19.1%). Of women who smoked when they became pregnant, those who quit in the month after a first missed period had a 40% increase in clubfoot risk and those who continued to smoke during the next 3 months had more than a doubling in risk, after controlling for demographic factors, parity, obesity, and specific medication exposures. Adjusted odds ratios for women who drank >3 servings of alcohol or coffee per day throughout early pregnancywere 2.38 and 1.77, respectively, but the numbers of exposed women were small and odds ratios were unstable.
CONCLUSIONS:
Clubfoot risk appears to be increased for offspring of women who smoke cigarettes, particularly those who continue smoking after pregnancy is recognisable, regardless of amount. For alcohol and coffeedrinkers, suggested increased risks were only observed in higher levels of intake.

Abstract
In the present review, we have examined the effects of coffee ingestion on fertility, reproduction, lactation and development. The potential effects of coffee consumption on fertility, spontaneous abortion and prematurity are not clearly established but appear to be quite limited. In rodents, caffeine can induce malformations but this effect appears in general at doses never encountered in humans. Indeed, as soon as the quantity of caffeine is divided over the day, as is the case for human consumption, the teratogenic effect of caffeine disappears in rodents. Coffee ingested during gestation induces a dose-dependent decrease in birth weight, but usually only when ingested amounts are high (i.e. more than 7 cups/day), whereas coffee has no effect at moderate doses. Caffeine consumption during gestation affects hematologic parameters of the new-born infant or rat. In animals, caffeine induces long-term consequences on sleep, locomotion, learning abilities, emotivity and anxiety, whereas, in children, the effects of early exposure to coffee and caffeine on behavior are not clearly established. The quantities of caffeine found in maternal milk vary with authors, but it appears clearly that caffeine does not change maternal milk composition and has a tendency to stimule milk production. In conclusion to this review, it appears that maternal coffee or caffeine consumption during gestation and/or lactation does not seem to have measurable consequences on the fetus of the newborn, as long as ingested quantities remain moderate. Therefore, pregnant mothers should be advised to limit their coffee and caffeine intake to 300 mg caffeine/day (i.e. 2-3 cups of coffee or 2.5-3 l of coke) especially because of the increase of caffeine half-life during the third trimester of pregnancy and in the neonate.

"Moreover, women with very high caffeine intake were more likely to have been obese and have partners who were obese and smokers, compared with those consuming less caffeine per day" If you take away their coffee without teaching them how to lose weight, they will eat more and be more obese and so will their children!! This article is the problem, not a solution!
