What is sleep training?

Sleep training involves teaching a baby to soothe themselves and fall asleep independently, without relying on external assistance like rocking, feeding, or being held. There are various sleep training methods, and we’ll be happy to discuss the most popular approaches later in the article.

Can you sleep train a 3- or 4-month-old?

According to the American Academy of Pediatrics (AAP), it is suggested to place babies in their sleep space when they are drowsy but not yet asleep, starting at around 4 months of age. This approach can benefit your baby by teaching them self-soothing techniques and can result in more restful nights for the entire family. When night wakings are reduced, everyone involved can enjoy evenings with more sleep.

However, this can be challenging if your baby is accustomed to falling asleep with assistance, as many babies are. The results of sleep training can vary for babies at 3 and 4 months old. Some babies may already have established sleep routines and respond well to sleep training techniques, while others may need more time before they can make significant improvements.

While sleep training at this age can help establish a foundation for healthy sleep habits, it is not a quick fix. Progress may not always be consistent. If you choose to sleep train your baby at this age, think of it as an opportunity for them to practice falling asleep on their own, without fully mastering the skill. Additionally, even if they learn to self-soothe at bedtime, they may still require some assistance during nighttime awakenings.

How long does it take to sleep train a 3- or 4-month-old?

Ah, the ever-changing world of baby sleep! It’s like navigating a rollercoaster ride with twists, turns, and the occasional loop-de-loop. At this age, expect ups and downs rather than a linear progression. Many babies may not fully develop the ability to self-soothe throughout the night until they reach six months old. However, 3- and 4-month-olds can often make progress in their ability to sleep independently at bedtime, which can later translate to improved sleep throughout the night.

The time it takes for your baby to adapt to new bedtime habits can vary from a few days to a couple of weeks, depending on the method you choose and your baby’s temperament.

Sample sleep schedule for a 3- or 4-month-old?

The optimal sleep schedule for your 3-month-old or 4-month-old will vary based on their individual needs. While their routine may still be unpredictable at this age, a typical day could follow this pattern:

– 7:00 a.m.: Wake up

– 8:30 a.m.: Nap

– 9:30 a.m.: Awake

– 11:00 a.m.: Nap

– 12:00 p.m.: Awake

– 1:30 p.m.: Nap

– 3:00 p.m.: Awake

– 4:30 p.m.: Nap

– 5:30 p.m.: Awake

– 6:30 p.m.: Bedtime routine

– 7:00 p.m.: Bedtime

This sample schedule assumes that your baby can stay awake for approximately 90 minutes at a time and takes around one-hour naps throughout the day. However, it’s important to note that babies of this age can handle awake periods lasting anywhere from 60 to 90 minutes, while naps may range from 30 minutes to two hours in duration.

Sleep training methods for 3 and 4-month-olds

Sleep training method Does it work for 3 and 4 month old babies?
Gentle methods, including the chair method and pick up put down Yes, these can be an effective way to help babies learn a new way of falling asleep at bedtime.
Ferber method or gradual extinction Yes, these methods can be used to help babies learn to fall asleep on their own. Generally, babies can make progress at bedtime but may not be able to fully drift back to sleep independently until they reach 6 months old.
Cry it out or total extinction Given that consistent progress is not usually expected at this stage of development, we don’t usually recommend CIO. If this approach is employed, we suggest monitoring progress through a video monitor with regular safety checks taking place at least every hour.

Gentle Approaches

Gradual sleep training methods, also known as “gentle” methods, involve guiding your baby towards developing independent sleep skills. Techniques such as the “chair method,” “fading,” and “pick up put down” focus on actively comforting your baby as they learn to fall asleep in a new way. These strategies can be used at bedtime and during the night, as long as your baby’s feeding needs are being met.

Gentle methods are particularly suitable for parents who prefer a tear-minimizing approach and are willing to invest extra time in the process. For example, if your baby usually falls asleep while being fed, you can start by transitioning to rocking them to sleep and gradually reducing the motion until you place them in the crib while they’re still awake. Throughout this journey, you can stay nearby to offer support, gradually reducing your touch and presence.

Gradual Extinction

In the realm of sleep training, graduated extinction strategies like the Ferber method involve placing your baby in their sleep space while they’re still awake. After saying goodnight, you periodically return for brief check-ins, starting with short intervals like 3 minutes on the first night and gradually extending the time between check-ins. Alternatively, some parents may prefer a consistent interval, such as 10 to 15 minutes.

This approach appeals to those seeking quicker results and who are comfortable with allowing their baby to cry for specific periods. It’s sometimes seen as a variation of “cry-it-out” (CIO), but different in that parents typically return at regular intervals to offer soothing comfort before leaving again.

Consistency is important during sleep training, but it may not always be possible for 3- and 4-month-olds. If you choose to use this method for your young baby, keep in mind that it’s normal for babies of this age to have difficulty consistently falling asleep on their own. You can always take a break if your baby is struggling on a particular night and opt for a gradual sleep training method instead (or try again the next night).

Cry-It-Out (CIO)

CIO, or “total extinction,” is a sleep training method that involves allowing your baby to fall asleep without attempting to soothe them. Before using this technique, make sure your baby is well-fed, dry, comfortable, and developmentally ready to fall asleep without assistance.

Place your baby in their crib while they’re still awake after the bedtime routine, then leave the room. To ensure safety, keep a video monitor in the room and conduct safety checks every hour. Some babies may fall asleep within 10 minutes, while others may cry for a longer duration.

We generally do not recommend this method at this age because many babies will struggle to consistently fall asleep on their own and may require help from their parents. This means that CIO may lead to prolonged crying without achieving a well-rested baby.

Sleep training tips for 3 and 4-month-olds

Tip #1: Expect ups and downs

At this age, sleep training can be a valuable tool on the path to establishing healthy sleep habits. However, not all babies are developmentally ready to consistently fall asleep on their own, so it’s important to remember that sleep training is not a quick fix. Progress is more likely to happen gradually over time rather than instantaneously resolving sleep issues.

Tip #2: Take breaks as needed

It’s common for your baby to struggle with falling asleep independently on some nights but not others. This is normal for young babies who are learning new sleep habits. If your baby is having a tough time on a particular night, you can take a 20-30 minute break and try again later. Alternatively, you can choose to help your baby fall asleep and attempt sleep training again the following night.

Tip #3: Pause before intervening

Babies often briefly stir or make sounds between sleep cycles. While it may be tempting to immediately intervene and assist your baby back to sleep during the night, it can be helpful to wait a few minutes before responding. Often, you’ll find that your baby settles back to sleep on their own without your intervention.

Can you sleep train 3- and 4-month-olds for naps?

It is usually easier to make progress with sleep training at bedtime, but if your baby’s night sleep is already fairly consistent, you can start laying the groundwork for better naps. Here’s how:

– Focus on having 1 or 2 naps in the crib per day (the first nap is often the easiest to sleep train).

– Establish a shortened version of your bedtime routine as a pre-nap routine to signal that it’s time to transition to sleep.

– Work on the nap for 30 minutes; if your baby hasn’t fallen asleep, leave the room and take a 30-minute break.

– Try again: Repeat the last couple of steps of the nap routine and give your baby another opportunity to fall asleep independently.

– If your baby still won’t nap after the second try, go ahead and help them fall asleep.

– If naps are shorter or skipped, consider moving bedtime earlier.

Can you sleep train during the 4-month sleep regression?

Yes, you can! The term “4-month sleep regression” is often used to describe a period of disrupted sleep patterns that some infants experience around the age of four months. It is not a clinical term but rather a colloquial phrase used by parents to refer to changes in their baby’s sleep habits during this developmental stage.

Between 3 and 4 months of age, infants undergo significant neurological and physiological changes. They start experiencing more mature sleep cycles, which include periods of lighter and deeper sleep similar to adults. As a result, their sleep patterns may become less predictable, and they may wake up more frequently during the night.

It’s important to note that not all babies go through a 4-month sleep regression, and the severity and duration of sleep disruptions can vary. Babies who rely on assistance to fall asleep at bedtime (such as rocking or feeding to sleep) are more likely to fully wake up between sleep cycles and seek help during the night to return to sleep.

If you’re experiencing sleep disruptions during this time, transitioning away from sleep associations at bedtime can be helpful. Although sleep may not be perfect at this age, it is likely to improve as your baby develops independent sleep skills.

How to sleep train 3- and 4-month-old twins?

You can make sleep training twins easier with these tips:

Coordinate sleep schedules: While twins may have individual sleep needs and patterns, try to coordinate their sleep schedules as much as possible. This helps manage your own sleep and ensures both babies get adequate rest. If one baby wakes up for a feeding or diaper change, briefly wake the other baby to sync their schedules. This prevents one baby from being awake while the other is sleeping, causing disruptions.

Prevent overtiredness: Babies who are overtired have a harder time falling asleep and staying asleep. Planning bedtime according to wake windows and sleepy cues can reduce tears caused by a mistimed bedtime. Use tools like the SweetSpot® sleep predictor to help determine the ideal bedtime for your babies.

Separate babies at bedtime: Whether you’re handling bedtime alone or have assistance, separating the babies during bedtime can make the process smoother. This allows each baby to work on developing independent sleep skills without disturbing their sibling.

What to do if sleep training for 3- and 4-month-olds is not working

If sleep training isn’t going as expected, consider the following:

– Aim for a sleepy but awake state: If your baby is consistently put down almost asleep, it can be difficult to make progress. Strive to place your baby in the crib while they are drowsy but still awake.

– Take a break if needed: If your young baby is struggling every night to fall asleep independently, causing stress for both of you, it’s okay to take a break. Try again in a week or two when your baby is a little older.

Takeaway: Sleep training 3- and 4-month-olds

Sleep training can establish a foundation for healthy sleep habits and help your baby learn how to self-soothe, leading to more peaceful nights for the entire family. While it may present challenges if your baby is accustomed to falling asleep with assistance, every baby is different at this age. Some may respond well to sleep training techniques, while others may need more time to make significant progress.

Remember, sleep training is not a magical fix, and progress may not always be smooth. Consider it an opportunity for your baby to practice the skill of falling asleep independently, even if they haven’t mastered it just yet. Don’t worry if they still require some support during nighttime wakings – that’s perfectly normal too! The path to success is as unique as your baby’s adorable little quirks.

Sleep Training FAQs for 3 and 4 Month Olds

Q: How can I sleep train my 3 and 4 month olds?

There are various methods available for sleep training. Some focus on gradual changes to minimize crying, while others offer a quicker approach that may involve more tears. Choose a method that resonates with you and serves as a framework for helping your baby learn to fall asleep independently without relying on your assistance.

Q: Are 3 and 4 month olds too young to sleep train?

While you can start sleep training at 3-4 months of age, it’s important to have realistic expectations. Many babies at this age will still require some assistance at bedtime and during the night, even with a consistent approach. Gentle methods like gradual fading or pick-up-put-down tend to work well, while intensive methods like total extinction may not be suitable. Consider your baby’s health and any sleep issues before beginning sleep training.

Q: How can I sleep train my 3 and 4 month olds without crying?

Various gentle sleep training methods, such as gradual fading and pick-up-put-down, can help minimize crying. However, it’s important to understand that babies may cry when their routines change, regardless of how gradual your approach is, and this is a normal part of the process. Establishing a consistent bedtime routine can provide comfort and assist your baby in learning to fall asleep independently.

Q: Should 3 and 4 month olds fall asleep on their own?

Some babies at this age can learn to fall asleep independently through practice. However, it’s important to recognize that not all babies can consistently achieve this milestone at this stage. When sleep training, it’s important to be patient as it takes time for babies to adapt to new routines and habits. Many babies at this age still benefit from nighttime feedings for better sleep.

Q: What is the best sleep training method for 3 and 4 month olds?

The “best” sleep training method for 3 and 4 month olds varies because each baby is unique and may respond differently. Choose an approach that aligns with your comfort level and is tailored to your baby’s specific needs and temperament.

Q: Is it harder to sleep train 3 and 4 month olds?

It’s important to manage your expectations when sleep training at this age. Babies are beginning to establish sleep patterns, and many can be receptive to bedtime sleep training methods at 3 and 4 months old. However, it’s common for infants at this age to still require parental assistance during nighttime awakenings.

Q: Can I use the cry-it-out method with 3 and 4 month olds?

Although some parents may choose the cry-it-out method (total extinction) to sleep train their 3 or 4 month olds, it is generally not recommended. Total extinction involves allowing the baby to cry themselves to sleep without providing any comfort or reassurance. This approach can be particularly challenging for parents at this age, and younger babies may struggle to consistently fall asleep independently.
