Instead of letting infants cry, American parents should keep their babies close, console them when they cry, and bring them to bed with them, where they'll feel safe, according to Michael L. Commons and Patrice M. Miller, researchers at the Medical School's Department of Psychiatry.
The pair examined childrearing practices here and in other cultures and say the widespread American practice of putting babies in separate beds -- even separate rooms -- and not responding quickly to their cries may lead to incidents of post-traumatic stress and panic disorders when these children reach adulthood.
The early stress resulting from separation causes changes in infant brains that makes future adults more susceptible to stress in their lives, say Commons and Miller.
"Parents should recognize that having their babies cry unnecessarily harms the baby permanently," Commons said. "It changes the nervous system so they're overly sensitive to future trauma."The two gained the spotlight in February when they presented their ideas at the American Association for the Advancement of Science's annual meeting in Philadelphia.
Commons and Miller, using data Miller had worked on that was compiled by Robert A. LeVine, Roy Edward Larsen Professor of Education and Human Development, contrasted American childrearing practices with those of other cultures, particularly the Gusii people of Kenya. Gusii mothers sleep with their babies and respond rapidly when the baby cries.
"Gusii mothers watching videotapes of U.S. mothers were upset by how long it took these mothers to respond to infant crying," Commons and Miller said in their paper on the subject.
The way we are brought up colors our entire society, Commons and Miller say. Americans in general don't like to be touched and pride themselves on independence to the point of isolation, even when undergoing a difficult or stressful time.
Despite the conventional wisdom that babies should learn to be alone, Miller said she believes many parents "cheat," keeping the baby in the room with them, at least initially. In addition, once the child can crawl around, she believes many find their way into their parents' room on their own.
American parents shouldn't worry about this behavior or be afraid to baby their babies, Commons and Miller said. Parents should feel free to sleep with their infant children, to keep their toddlers nearby, perhaps on a mattress in the same room, and to comfort a baby when it cries.
"There are ways to grow up and be independent without putting babies through this trauma," Commons said. "My advice is to keep the kids secure so they can grow up and take some risks."Besides fears of dependence, the pair said other factors have helped form our childrearing practices, including fears that children would interfere with sex if they shared their parents' room and doctors' concerns that a baby would be injured by a parent rolling on it if the parent and baby shared the bed. Additionally, the nation's growing wealth has helped the trend toward separation by giving families the means to buy larger homes with separate rooms for children.
The result, Commons and Miller said, is a nation that doesn't like caring for its own children, a violent nation marked by loose, nonphysical relationships.
"I think there's a real resistance in this culture to caring for children," Commons said. But "punishment and abandonment has never been a good way to get warm, caring, independent people."
