Mothers who drink a moderate amount of coffee during pregnancy will not have newborns with sleeping problems, a Brazilian study suggests. Dr. Ina Santos and colleagues at the Federal University of Pelotas in Brazil studied sleeping patterns of more than 4,200 infants until the age of 3 months. The study also considered the caffeine-consumption habits of their mothers both before and after delivery. The results which appeared in the journal pediatrics couldn’t find any difference between the sleep patterns of babies whose mothers drank coffee during and after pregnancy. Infants whose mothers consumed greater amounts of caffeine woke up slightly more often than those whose mothers drank less coffee. “Maternal caffeine consumption, even in large amounts during gestation and lactation, had no consequences on sleep of the infant at 3 months of age,” the researchers wrote. “Caffeine consumption during pregnancy and by nursing mothers seems not to have consequences on sleep of infants at the age of three months.” The study did not focus on other potential consequences of mothers’ caffeine intake for children’s health. High caffeine intake can also harm women’s own health and cause problems such as sleep disturbance. Considering the overall findings from different studies, heath experts suggest mothers to limit their daily caffeine intake to a moderate level which they say is 300 mg of caffeine or less each day.
