Singer Jessie James Decker got major flack, she told People, for drinking a glass of wine while breastfeeding five-month-old Forrest Bradley–a moment which was immortalized in a photo last month. The case echoes another from 2014, when Tasha Adams, a 28-year-old mother of three was arrested for allegedly endangering the welfare of her then-six-month-old daughter after drinking while breastfeeding at an Arkansas restaurant. The charges were eventually dropped; drinking while nursing isn't illegal in Arkansas. What Our Obsession With Breastfeeding Is Really Doing to Moms and Their Babies How Much Alcohol is Too Much in Breastmilk? Drinking while nursing may not be illegal, but experts say large amounts of alcohol can be harmful to a breastfeeding baby. So are smaller amounts safe? And if so, how much is too much? That's less clear. "It's definitely gray," said Catherine Herway, MD, a maternal-fetal medicine specialist with CrystalRun Healthcare in Middletown, New York. There just aren't enough good-quality studies to give us the full picture, she added. While some evidence indicates that a baby's growth and motor function may be negatively impacted by 1 drink or more daily, other studies have not confirmed these findings. Mothers of newborns less than three months old should be extra careful about drinking, as the baby's brain is still developing and very vulnerable, said Beth Conover, a nurse practitioner at the University of Nebraska Medical Center in Omaha. According to the Centers for Disease Control and Prevention (CDC) exposure to alcohol above moderate levels (defined as up to 1 standard drink per day) through breast milk could be damaging to an infant's development, growth, and sleep patterns. In addition, the CDC points out, that this level of alcohol consumption could impair a mother's judgment and compromise the safety of the child. And other evidence shows that more than 2 drinks daily appears to decrease the length of time that mothers breastfeed their infants. A 2018 study published in Pediatrics found mental development issues in children who had been exposed to alcohol through breast milk: At ages 6 and 7, these children did not perform as well as other children on reasoning tests. The American Academy of Pediatrics (AAP) states that consuming alcohol of any kind may decrease the amount of milk your baby drinks. A New Marijuana Study Found THC in Breast Milk up to 6 Days After Moms Used the Drug Can Alcohol Help With Breastfeeding? Unfortunately, it's an old wive's tale that a small amount of alcohol can actually help milk letdown or the release of milk. In fact, the CDC says that higher levels of alcohol consumption can interfere with letdown while maternal alcohol levels are high. While some people believe that drinking beer will increase your milk supply, the AAP emphasizes that drinking beer does not increase your milk supply. Researchers note that polysaccharides from barley and hops are responsible—so non-alcoholic beer has the same effect. That said, there are ways to drink responsibly without endangering your baby. Here are three things you need to know about alcohol and nursing. Less Is More Breastfeeding or not, women and men should not drink more than the amounts recommended by leading health organizations, said Conover. For women, that's one drink per day. The CDC says that not drinking alcohol is the safest option while breastfeeding. However, moderate drinking (defined as up to 1 standard drink per day) is not known to be harmful to the infant, especially if you wait at least 2 hours after a single drink before nursing. Here's What Really Happens to Your Brain When You Drink Too Much Alcohol Timing Is Key It's probably best not to breastfeed your baby as you're drinking or right after drinking. "If a mom is going to drink alcohol, she should wait at least three to four hours until breastfeeding the baby," said Dr. Herway. (The CDC says to wait a minimum of two hours.) "The amount of alcohol in breast milk is very similar to the amount in the woman's blood and alcohol is a fast-acting drug," explained Conover. "It peaks pretty fast after you drink... It moves in and out of milk." Alcohol could take longer to peak in some women, so pay attention to how you feel in addition to how long it's been since you finished your drink. "If you're still feeling woozy, it's like the canary in the coal mine," said Conover. "The alcohol level is [still] too high in the bloodstream and in the breast milk." The 4 Best Breast Pumps, According to Experts Plan Ahead When Possible If you know you're going to drink and your baby will need to eat not long after, make sure you have some stored breast milk or formula ready to go, said Conover. If you do bottle-feed your baby after having a drink, you can "pump and dump" to alleviate breast pain that may result from skipping a feeding. "We get a lot of calls [from mothers] on St. Patrick's Day and New Year's Eve," said Conover. "They're calling because they'd like to still have a life and they want to take good care of their babies. They're responsible." Decker stressed to People that she, too, is responsible–and unapologetic. "I know I'm a great mother, there's not one doubt in my mind. I know that I take care of my babies, I know that they feel loved and they feel happy. So if I want to have a cocktail to celebrate my husband doing something great in his work, I'm going to, and I can still breastfeed."
