Crying it out has been proven time and time again to cause unfavorable changes in brain chemistry.
Denmark is officially moving away from the cry it out method after a nationwide study revealed it was still being taught in most municipalities. More than 700 psychologists signed a unified statement urging immediate discontinuation of the practice. They emphasized that prolonged crying without comfort elevates cortisol and affects how the infant brain forms emotional and stress regulation pathways. This national push reflects growing scientific awareness of early neural sensitivity.
Researchers highlight that when babies cry alone, their stress signals rise sharply. Without caregiver response, the brain begins wiring for self protection rather than trust. These early patterns influence later attachment styles emotional stability and even learning behavior. Denmark’s decision aligns with decades of neuroscience showing that infants depend on caregiver regulation to build healthy neural circuits.
Despite this, the cry it out approach continues to be recommended in parts of the U.S. where outdated models of infant independence remain common. Scientists argue that babies do not learn self soothing through isolation. Instead they learn through repeated experiences of comfort which stabilize heart rate breathing and emotional processing. This helps form long term resilience.
Denmark’s shift highlights a global conversation about infant well being. The science is clear. Responding to a baby’s distress supports healthier development than leaving them to cry alone.
