Research led by Jennie Rosier, an associate professor at James Madison University, is questioning the validity of the popular cry-it-out sleep training method for infants in the U.S. In her book, “Dispelling Cry-It-Out Sleep Training Myths and What to Do Instead,” Rosier and her team of interdisciplinary scholars argue that frequent night waking in infants is a developmentally normal occurrence rather than an issue requiring intervention.

Rosier's research challenges the prevailing belief that sleep training is essential for managing infant sleep challenges. The authors examined a variety of disciplines, including psychology, neuroscience, anthropology, and attachment theory, indicating that waking at night is a typical aspect of infant growth. They explored the historical roots of cry-it-out techniques, analyzed their claimed effectiveness, and discussed how these methods may be at odds with the emotional and biological needs of infants. The book suggests alternatives that foster infant sleep while maintaining caregiver responsiveness and attachment security.
In discussing their findings, Rosier pointed out that the book draws from a broad spectrum of research rather than primarily relying on sleep-training studies. This includes developmental research supporting the notion that fragmented sleep and signaling for caregiver support are standard in infancy and attachment research that underscores the importance of caregiver responsiveness during distressing moments. The book critically reviews existing cry-it-out efficacy studies, highlighting methodological issues and questioning whether decreased crying correlates with improved emotional well-being.
Rosier notes that mainstream sleep training often mistakenly assumes infants should learn to sleep independently. The book counters this notion by asserting that dependence and night waking are expected developmental behaviors. While some pediatric recommendations focus on fostering independent sleep from an early age, Rosier's team advocates for a more responsive approach, emphasizing co-regulation and developmentally appropriate expectations regarding infant sleep.
Parents are encouraged to understand that responding to their baby's needs doesn't conflict with achieving better sleep for themselves. The book advises parents to set realistic expectations about sleep, acknowledging that night waking is a normal aspect of infancy and that sleep consolidation evolves over time, not through training. It offers practical solutions that promote sleep through connection and environmental adjustments without resorting to cry-it-out methods.
Looking forward, Rosier hopes for a shift in the perception of infant sleep, advocating for a view that sees it as a natural part of human development rather than a problem to solve. She calls for more comprehensive training for healthcare providers regarding infant sleep dynamics, attachment, and neurodevelopment, emphasizing the need for guidance that aligns with current research rather than outdated beliefs. Ultimately, she aims to empower parents with knowledge, freeing them from the pressure of conformity and affirming their instinctual approach to their child’s needs.
