Can I Let My Baby Cry It Out?

Is Extinction Sleep Training Safe and Effective?

Extinction sleep training, often referred to as the "cry it out" method, is a technique where parents allow their baby to cry without intervention until the baby falls asleep. This method aims to help babies learn to self-soothe and fall asleep independently. While it has been a topic of debate, recent studies and statistics provide valuable insights into its safety and effectiveness. This article will explore the evidence, the pros and cons of the "cry-it-out" sleep training method, as well as alternatives.

Effectiveness

Research consistently shows that extinction sleep training can be effective in improving infant sleep patterns. A study published in Pediatrics found that infants who underwent extinction sleep training experienced significant reductions in sleep latency (the time it takes to fall asleep) and night wakings[1]. Parents reported that their babies were able to sleep through the night more consistently, leading to better overall sleep quality for the entire family.

Another study highlighted that 82% of parents who used the extinction method reported noticeable improvements in their baby's sleep within one week[2]. This rapid improvement can be particularly beneficial for sleep-deprived parents seeking quick results.

Safety and Emotional Impact

One of the primary concerns about extinction sleep training is its potential impact on a baby's emotional well-being. Critics argue that leaving a baby to cry can lead to increased stress levels and negatively affect the parent-child bond. However, recent research suggests otherwise. A 2020 study published in the Journal of Child Psychology and Psychiatry found that occasional use of the cry it out method did not harm attachment or behavioral development at 18 months[3]. Babies who underwent sleep training showed no differences in attachment security compared to those who did not.

Additionally, a study measuring cortisol levels (a stress hormone) in infants found that while there was an initial increase in cortisol during the first few nights of extinction sleep training, levels returned to baseline within a week[4]. This indicates that babies can adapt to the new sleep patterns without experiencing long-term stress.

Parental Well-Being

Sleep deprivation can significantly impact parents' mental and physical health. Studies have shown that successful sleep training, including the extinction method, can improve parental well-being.

Parents who implemented sleep training reported a 50% reduction in symptoms of postpartum depression. Improved sleep quality for both the baby and parents can lead to better mood, reduced stress, and enhanced overall family dynamics.

Alternatives

While extinction sleep training can be effective, it is not the only approach to sleep training. Gentler methods, such as graduated extinction, leave and check methods, and bedtime fading have also been shown to improve infant sleep without leaving babies to cry for extended periods. These methods involve allowing the baby to self-soothe for set increments of time; gradually increasing the time between comforting the baby; or adjusting bedtime routines to help the baby learn to fall asleep independently.

Cons of Extinction & Solutions

Extinction can be effective, but the emotional toll it takes on parents during the process can be discouraging. Some parents may give up without support. Also, babies could wet their clothes, poop, become sick, or be uncomfortable in other ways that parents are not aware of because they don’t respond to their babies’ cries. 

Leave and check methods help to alleviate these concerns and ensure that babies are healthy, safe, and comfortable during the process. Utilizing a proven sleep training program or personalized guidance from a baby sleep consultant can provide the fastest and most effective results for most families.
