As a sleep consultant, one of the most common questions I get from parents is, “Is sleep training safe for my baby?” This concern is completely understandable. Parenting can be overwhelming, and sleep training can sometimes feel like a big, unfamiliar step. However, the truth is that sleep training, when done correctly, is safe, effective, and beneficial for both babies and parents. In fact, the research all supports that sleep training can lead to better sleep, improved health, and a stronger parent-child bond.
In this blog, I’ll walk you through the research and evidence behind sleep training to help you feel confident and informed about what it really means for your baby’s sleep.
What Is Sleep Training?
At its core, sleep training refers to a set of techniques designed to help babies learn to fall asleep independently and soothe themselves back to sleep when they wake during the night. Sleep training methods vary, but they generally aim to teach babies how to self-soothe without relying on external sleep associations, like rocking or feeding.
While some sleep training methods involve allowing babies to cry for short periods (commonly known as controlled crying), other methods are gentler and involve less crying. The key point is that sleep training is not about leaving your baby to cry it out for long periods. Instead, it’s about providing the structure and support necessary for your baby to develop healthy sleep habits in a safe and loving environment.
Is Sleep Training Safe? The Research Says Yes
Over the past few decades, there has been a growing body of research on the safety and effectiveness of sleep training. Let’s take a closer look at some of the key studies that can help reassure you.
1. No Long-Term Harm to Babies
One of the biggest concerns parents have about sleep training is whether it will have a negative impact on their baby’s emotional well-being or attachment. According to a 2016 study published in the American Journal of Paediatrics, sleep training methods—such as controlled crying or gradual sleep training—do not negatively affect a child’s emotional development or attachment to their parents.
In fact, the study found that babies who were sleep trained experienced better sleep quality and improved overall health without any long-term emotional harm. The researchers concluded that sleep training, when done correctly and with appropriate care, is a safe method for promoting healthy sleep habits.
2. Improved Sleep for Parents and Babies
Sleep deprivation is a serious issue for many new parents, and research consistently shows that sleep training can lead to better sleep quality for both parents and babies. A study published in the Journal of Sleep Research found that sleep training improved sleep for both parents and children by helping babies fall asleep faster, stay asleep longer, and experience fewer night wakings.
Better sleep is not just about feeling more rested—it has significant benefits for health, mood, and cognitive function. For babies, sleep is crucial for brain development, memory consolidation, and physical growth. For parents, better sleep means improved mental health, lower stress levels, and a better ability to care for their child.
3. Gentle Methods Are Just As Effective as More Structured Techniques
For parents who are wary of methods that involve any crying at all, there’s good news: gentle sleep training methods—such as the Ferber Method’s graduated approach or the Chair Method—have been shown to be just as effective as more traditional techniques, without the need for prolonged crying.
A study in the Archives of Pediatric and Adolescent Medicine found that babies who used more gradual approaches to sleep training, such as staying in the room while gradually reducing parental involvement, experienced significant improvements in sleep quality. These methods still helped babies learn to self-soothe and fall asleep independently, without the distress that some parents fear.
4. Sleep Training Helps Prevent Sleep Issues from Persisting
Another important aspect of sleep training is that it can prevent sleep problems from continuing into toddlerhood and beyond. According to the American Academy of Sleep Medicine, babies who are taught to fall asleep independently at an early age are less likely to develop long-term sleep problems, such as insomnia or sleep regression, as they grow older.
By establishing healthy sleep habits early on, you’re setting the foundation for better sleep as your child develops. This can help prevent future sleep challenges and promote better overall health and well-being for your child as they move through different developmental stages.
