Police had been called to her home in Grand Forks, N.D., on an unrelated domestic disturbance call, and while they were there, an intoxicated Anvarinia began to breastfeed her 6-month-old child. The officers learned from a local hospital that breastfeeding while under the influence of alcohol was not good for the child, and they charged her with neglect.
While Anvarinia's was an extreme case, the truth is that most mothers are not teetotalers, nor are they expected to be. But there are no consistent guidelines regarding alcohol consumption following pregnancy during the time when mothers may be breastfeeding.
While the ideal postpartum abstention from alcohol, since ethanol can move rapidly into the breast milk, lactation experts agree that moderate alcohol consumption by a mother does not pose major threats to an infant.
"Breastfeeding is not a prison for women," said D. Miriam Labbok, director of the Center for Infant and Young Child Feeding and Care at the University of North Carolina at Chapel Hill. "It depends how much [the mother] ingested and over how long."
Alcohol Is Easily Absorbed By Infants
Ethanol from alcoholic drinks can move quickly into breast milk from the mother's bloodstream within an hour of ingestion. Depending on the person's metabolism and how much alcohol was consumed over time, it can take two or more hours for the alcohol to leave the mother's system. If a child is breastfeeding during this time, they can receive up to about one fifth of the amount present in the blood.
"If the mom has a dose, the baby gets a dose," Labbok said. "It adds up."
Despite receiving far less concentrations than the mother, the alcohol can hit a child harder because they are smaller and their livers are not developed enough to properly metabolize the alcohol. Therefore, the compounds remain in the infant body longer.
In Anvarinia's case, breastfeeding while intoxicated turned out to be a Class C felony, in which there is a failure to provide proper parental care and control.
Moderation Is Key For Mothers
"A mother who has a glass of wine with dinner or one beer when she goes out is not an issue or a problem," said Marsha Walker, a registered nurse and a member of the board of directors for the Massachusetts Breastfeeding Coalition. "The problem is if she is an alcoholic, if she's unable to drive or care for a baby. At that point in time, she's better off waiting to breastfeed until [the alcohol] has cleared out."
Excessive alcohol, when transferred to a breastfed baby, can depress the central nervous system and cause drowsiness and deep sleep, abnormal weight gain, and, in extreme cases, retarded mental or motor development. And for the mother, intoxication can stem milk production, leaving her unable to feed a baby, if necessary.
Mothers are educated about alcohol consumption prenatally but the sources for information on booze after birth are more scattered.
"It isn't emphasized at that point in time [postpartum] and the mothers are already overwhelmed," said Walker, but pointed out that the topic can come up prenatally in breastfeeding or childbirth classes.
Preparations before having a few drinks can go a long way towards ensuring no alcohol gets into the baby's system. Lactation experts suggest pumping and freezing breast milk or having formula on hand can be useful if the mother will be drinking.
"But should she not feed if she has some drinks? No, she should feed the baby," Labbok said. "It's not called unsafe by anybody... Women around the world continue their normal lifestyles while breastfeeding."
