When Can Sleep Training Start?

When Can Sleep Training Start?

Sleep training can generally start when your baby is around 4 to 6 months old. At this age, infants are typically capable of sleeping for longer stretches at night and may no longer need nighttime feeds for nutritional reasons. However, it is important to consider that every baby is unique, and developmental readiness can vary.

Understanding Sleep Training

Sleep training refers to techniques that help babies learn to fall asleep and stay asleep on their own. While this might sound simple, it tends to be a sensitive topic for many parents. Different methods cater to varying parenting styles and baby temperaments, so understanding the basics can help make an informed choice.

Developmental Readiness

As previously mentioned, around 4 to 6 months is generally considered the appropriate time to start sleep training. But why is this specific timeframe chosen? Here’s why:

Firstly, by this age, a baby’s circadian rhythm, or internal clock, begins to regulate more clearly. This means that they start distinguishing between day and night, making it easier to create a sleep schedule.

Second, babies’ stomachs are growing, allowing them to intake more during feedings and go longer between them. This can reduce the number of night feedings needed, setting the stage for longer sleeping intervals.

Lastly, babies around 4 to 6 months old begin to develop self-soothing skills like sucking their thumbs or cuddling a blanket. These skills are important for falling back asleep without parental intervention.

The Role of Individual Differences

Even though 4 to 6 months is the guideline, it’s critical to look for signs of readiness specific to your baby. Does your baby show the ability to self-soothe at times? Are they moving towards a more regular sleep pattern on their own? Pediatric approval is also advisable to ensure your baby is ready for sleep training.

Types of Sleep Training Methods

There are several different methods of sleep training, each with varying approaches and philosophies. Understanding these can help you make the best choice for your family.

Cry It Out (CIO) Method

Often referred to as the “Ferber Method,” this approach involves letting the baby cry for specified periods before offering comfort. The intervals gradually increase in duration, teaching the baby to self-soothe.

While some parents find this method effective, others may find it too heartbreaking. Emotional readiness for this technique is crucial for parents.

No-Tears Method

This method tends to involve co-sleeping arrangements or staying by the baby’s side until falling asleep. It focuses on creating a soothing environment through gentle comforting techniques like rocking and patting.

This method can be time-consuming and may require more patience but is usually less stressful for both parent and child.

Pick Up/Put Down Method

In this middle-ground approach, you pick up the baby when they start crying but put them back into the crib once they are calm. This process is repeated until the baby eventually learns to soothe themselves without needing to be picked up.

Creating the Sleep Environment

Regardless of the sleep training method chosen, creating an ideal sleep environment is fundamental. Your baby’s sleeping area should be conducive to restful sleep. Here’s how to achieve that:

Darkness and Light Control

You want to associate darkness with sleep time and lightness with wake time. Using blackout curtains can help control the environment. For naps, ensuring that the room is somewhat dark can also help establish a consistent sleep pattern.

White Noise

Using a white noise machine can mimic the sounds that babies heard in the womb, creating a comforting and consistent background noise. This can drown out other distracting noises in the household and help maintain a sound sleep environment.

Safe Sleeping Practices

Always follow safe sleep guidelines, such as laying the baby on their back and ensuring the crib is free from soft toys, heavy blankets, or bumpers. These practices help in reducing the risk of sudden infant death syndrome (SIDS).

Establishing a Routine

A consistent bedtime routine can play a huge role in successful sleep training. It signals to your baby that it’s time to wind down and sleep, creating a sense of predictability.


A warm bath can be a relaxing activity to include in your pre-bedtime routine. The drop in body temperature after a bath can make babies feel sleepy.


While avoiding night feeds is the goal, a final feed before laying your baby down for the night can ensure they go to bed with a full stomach, reducing the likelihood of waking up due to hunger.

Reading and Singing

Calming activities such as reading a book or singing lullabies help ease the transition from wake time to sleep time. These activities can be comforting and help foster a strong emotional bond.

Addressing Challenges

Sleep training is rarely a straightforward journey and may come with challenges. Being prepared mentally and emotionally can significantly help in overcoming these obstacles.

Teething and Illness

There will be phases such as teething, growth spurts, or illness where sleep training routines may be disrupted. It’s okay to take a step back and comfort your baby more during these times.


One of the most critical elements in sleep training is consistency. It can be tempting to break from the routine, but inconsistent application can confuse your baby and delay progress.

Parental Stress

Sleep training can be stressful, not just for the baby, but also for the parents. Taking care of your emotional well-being is essential. Support groups, parenting forums, or consulting a pediatric sleep specialist can provide valuable assistance.

Tracking Progress

Documenting sleep patterns and behaviors can help you track progress over time. Look for improvements in how long it takes for your baby to fall asleep, how many times they wake up, and how quickly they can return to sleep.


Based on your tracking, make minor adjustments as needed. If a particular method is not working after a reasonable amount of time, it might be worthwhile to switch techniques or combine methods for better results.

Professional Guidance

If sleep training seems overwhelming or if you face persistent issues, don’t hesitate to seek professional guidance. Pediatricians and sleep consultants can offer specialized advice tailored to your baby’s needs.

Finishing Thoughts

Starting sleep training for your baby is a significant milestone that often comes with a mix of challenges and rewards. The window of 4 to 6 months offers a good starting point, but understanding your baby’s unique readiness cues and consulting with healthcare professionals are key to a successful transition. From choosing the right method to creating an optimal sleep environment and maintaining consistency, each step plays a critical role in your journey. With patience and persistence, you can look forward to more restful nights, both for you and your baby.
