Debunking the Myth: Sleep Training and Childhood Trauma

While sleep training can be a contentious topic among parents, scientific research suggests that when done properly and with care, sleep training does not cause trauma or lasting harm to children. Let's delve into the scientific evidence and address the concerns surrounding sleep training.


Understanding Sleep Training

Sleep training involves teaching babies or young children to self-soothe and develop healthy sleep habits. It comes in various methods, including extinction (CIO), controlled comforting, or the Ferber method. These methods aim to help children learn to fall asleep independently and soothe themselves back to sleep when waking during the night.


The ability for babies to self-soothe independently can vary widely based on individual development and temperament. Generally, babies start developing self-soothing skills around 3 to 6 months of age, but this varies significantly among infants.


Expert Tip: Laying Foundations for Self-Soothing

What is Self-Soothing look like? Sucking, rocking, or humming can all be soothing. Babies naturally learn this skill over time, and it's a crucial part of healthy sleep habits.


Building Healthy Foundations: Supporting your baby's ability to self-soothe begins early. Encourage practices such as putting your baby down awake, allowing them to learn how to settle themselves to sleep. Responding to their needs while gradually giving them space to self-soothe fosters independence and healthy sleep patterns.


Around 3 to 4 months, babies might begin showing signs of self-soothing, such as sucking on their fingers or fists, rubbing their faces, or finding comfort in a sound or rhythmic motion. By 6 months, most babies can start learning to fall asleep on their own and self-soothe back to sleep when they wake during the night.


However, full independent self-soothing where a baby consistently settles themselves to sleep without any parental intervention might not fully develop until closer to 9 months or even later for some children.


It's essential to remember that the ability to self-soothe is a learned skill that can take time and practice for babies to master. Additionally, parental responsiveness and providing a secure and nurturing environment play a significant role in supporting a baby's ability to develop self-soothing skills.


Scientific Evidence and Research Findings

Numerous scientific studies have explored the effects of sleep training on children's emotional well-being, and the consensus is reassuring:

  1. No Lasting Harm: A study published in the journal "Pediatrics" found that sleep training had no adverse long-term effects on children's emotional health, behavior, or parent-child attachment. It showed that infants who underwent sleep training had no increased risk of anxiety, depression, or behavioral issues later in childhood.

  2. Positive Outcomes: Research conducted at Australia's Flinders University found that children who underwent sleep training experienced improvements in sleep duration, night awakenings, and overall sleep quality. These improvements positively impacted both the child's and parents' well-being without any indication of psychological harm.

Expert Tip: Choosing the Right Method for Success

Method Matters: Selecting the appropriate sleep training method tailored to your child's temperament and your family's preferences can significantly impact the success of the process. Factors such as your child's age, temperament, and your parenting style should guide the choice of method. Gradual methods like controlled comforting might suit some children, while others might respond better to a more gentle approach, such as the fading method. Understanding your child's needs and tendencies will play a pivotal role in achieving successful sleep training outcomes.


  1. Parental Stress Reduction: A study published in the "Journal of Developmental & Behavioral Pediatrics" revealed that successful sleep training reduced parental stress levels and improved the parent-child relationship, contributing to a more positive family dynamic.

  2. Regulation of Stress Response: Research suggests that teaching infants to self-soothe through sleep training can help them learn self-regulation skills and manage stress responses more effectively over time.

Sleep Training and Child Well-being

In conclusion, reputable scientific studies indicate that when conducted with sensitivity and responsiveness to a child's needs, sleep training does not lead to trauma or long-term harm. Instead, it can foster healthy sleep habits and contribute to a more positive family environment.
