What Is the Cry-It-Out Method?

The cry-it-out method, or CIO, is a sleep-training technique in which the little one learns to self-soothe to fall asleep. This involves the baby crying before finally falling asleep. The technique basically involves the baby crying because the parent does not attend to the child as the child falls asleep. The CIO method principle says that sometimes the baby cries because they do not require food, are not in pain, or are not in a dangerous situation. They are merely adjusting to falling asleep alone.

Essentially, the cry-it-out technique boils down to:

  • You place the baby down to sleep while they are awake but sleepy.
  • You leave the room.
  • When the child cries, one does not rush to pick up the baby.
  • Eventually, the child will learn to calm down on their own, meaning they will learn to fall asleep on their own.

There can be several variations within the CIO, ranging from quite gradual to more immediate. Some techniques include checking on the baby occasionally, and then there might be no checks at all. The common theme for all versions could be helping the baby acquire independent sleep.

It is essential to understand that CIO is not a form of neglect. This method is adopted after the needs for feeding, comforting, and protecting are fully met, once the baby has reached their developmental milestones.

How Does the Cry-It-Out Method Work?

Even if one wonders which exact steps must be followed for the chosen technique, in general, all CIO variants share a common structure.

Step 1: Having a Consistent Bedtime Routine

Before practicing CIO, a soothing bedtime routine is established by the parents.

This may include:

  • Taking a warm bath.
  • Giving babies a massage.
  • Feeding them.
  • Reading a book or singing a baby lullaby.

An established routine is a clear indicator to the baby that sleep time is nearing.

Step 2: Place Baby in Crib While Awake

The baby is put in the cot while still awake but sleepy, not completely asleep. This is very important because the aim is for the baby to acquire the ability to put himself/herself to sleep.

Step 3: Exit the Room

As soon as the baby is secure in the crib, the parent exits the room. The little one might start crying or make a fuss.

Step 4: Crying Allowed (With or Without Monitoring)

According to the selected technique:

  • Parents might take breaks for defined periods before their checks.
  • Or they may just let it be and not check.
  • Crying episodes normally decline gradually as the baby develops the skill of self-soothing.

Step 5: Nightly Consistency Over a Period

CIO is not a quick fix. Several nights, or occasionally a week or so, might be required for the sleep pattern to improve. The main factor here is staying consistent.

What Are the Different Types of Cry-It-Out Methods?

The different types of cry-it-out methods are

1. Ferber Method:

The Ferber method is also known as “Graduated Extinction.” Richard Ferber is its developer and a child specialist. This approach focuses only on teaching children how to fall asleep on their own. So, here's how you do this: you leave your child alone when they cry for short intervals, which are the first three minutes. Later, you go in for five minutes, then in ten minutes.

When you come back to check on them, make sure to comfort your baby. You don’t have to pick them up. You can just be there, even if you are talking softly to the baby. Really, all this is a means to help the baby and the parents become a little more comfortable with this sleeping process. The final aim here, over time, would be to help the baby become more comfortable sleeping on their own.

2. Weissbluth’s Method:

The way Marc Weissbluth prescribes is on the extreme spectrum of the thing, like, complete extinction. Here's the basic idea: The baby is placed in the crib while still awake, which helps them learn to fall asleep independently.

Finally, here’s the kicker: parents are not allowed in the room until morning, except in emergencies. The main thing this method aims for is making sure the little one gets enough naptime throughout the day and gets to bed early. This way, you can help avoid that overtiredness that often just leads to more crying. It's all about keeping a good routine.

3. Murkoff’s Method:

Heidi Murkoff, that parenting guru you turn to for advice, is all about the cry-it-out approach but with a twist. But how is this done, exactly? Well, the parents can let the children cry for a short while. When the baby is wailing away, that is when the parents chime in.

The primary goal here is to learn as much as possible about your baby's personality and to respond to them in a way that feels right for both of you. It is not about following rules but listening to your heart. After all, no two babies are the same, and what may go for them may not go for others. It is quite a relief to know that there is someone out there who thinks along these lines.

4. Bucknam and Ezzo’s Method:

This approach, developed by Robert Bucknam and Gary Ezzo, involves exclusively combining feeding sessions with sleep training. Here’s how it works:

The baby follows a routine diet and sleeping pattern. This can really be beneficial. When it’s time for the baby to sleep, a little crying is okay. In fact, this crying helps the baby learn how to self-soothe. And, parents should not give the baby a meal to put them to sleep.

In a nutshell, it is all about routine and predictability. This approach is all about assisting you to get a good rhythm going with your little one.

5. Hogg and Blau’s Method:

Tracy Hogg and Melinda Blau devised a more gentle approach, often referred to as “pick up, put down.”

Here it goes:

  • Place the baby in the crib when they are still awake.
  • If the baby cries intensely, pick them up and comfort them.
  • After the baby has calmed down, put them back in the crib.
  • Repeat this process until the baby learns how to sleep on their own.

This technique is considered a compromise between the 'cry it out' and 'no cry' methods of sleep training.

6. Giordano and Abidin’s Method:

The approach Michelle Giordano and Richard Abidin refer to pinpoints emotional readiness.

Here's the thing:

  • Parents are advised to monitor their own stress levels and their baby’s while undergoing sleep training.
  • The emotional well-being of everyone in the process must be taken into consideration.
  • Methods such as CIO must be adjusted based on the baby's and parents' reactions, not just followed to the letter.
  • The emotional well-being of parents must be considered alongside the household's general dynamics.

The aim is to ensure that sleep training improves sleep without increasing household stress.

How Does Cry-It-Out Help Babies Sleep?

When we observe this from a child development perspective, the cry-it-out method definitely works for babies to learn these essential self-soothing techniques. Let’s just think about this for a minute; babies aren't automatically versed in slipping away to sweet dreams on their own. In most cases, they rely on stuff like rocking, feeding, or cuddling to help them fall asleep.

Thus, if these comforts are removed, the baby may begin to cry. It is a form of protest. However, through some repetition, the baby actually learns to self-soothe. Soon enough, the baby will be able to sleep on their own.

Crying while following the cry-it-out method isn’t always an indicator of distress or an issue with your baby. Often, it simply means they are frustrated with the adjustment process. However, as the child gets used to the routine, the crying eventually subsides, and the child can fall asleep easily.

When Should You Start Cry-It-Out, and Who Is It Best For?

Appropriate Age:

Almost all experts agree that it’s not an appropriate technique to apply to babies.

Now, if we analyze by age group:

  • Under 4 months: No go.
  • 4 to 6 months: You can introduce some gentle methods.
  • 6 months & above: That is generally when CIO is recognized as acceptable.

At this point, they are usually able to:

  • Go longer stretches of time without needing those late-night feedings.
  • Self-soothe for little bits of time.
  • Better recognize the cues for sleeping.

A CIO might be very useful for babies who wake up throughout the night but do not have any medical problem causing the waking. Conversely, if the family is feeling the effects of sleep loss, CIO could be worth looking at for children who are extremely dependent on sleep associations.

But for Whom Is CIO Contraindicated?

  • Absolutely newborns.
  • Babies with medical issues, reflux, or who are not gaining weight well.
  • When the families are already stressed or anxious about their crying babies, then this is a method to avoid.

Every family's different, so it's always good to consider what works best for your situation.

What Are the Benefits of the Cry-It-Out Method?

Many parents prefer the CIO method primarily because of the advantages it offers.

  • Improved Nighttime Sleep:

The child can sleep for longer periods with fewer night awakenings.

  • Faster Sleep Onset:

Children can learn to fall asleep faster.

  • Improved Daytime Mood:

Well-rested children are in a better mood and are less cranky.

  • Improved Feeding Habits:

Sleep can improve children’s feeding habits.

  • Improved Health of Children’s Napping Patterns:

Improved nighttime sleep can improve children’s napping patterns.

  • Improved Parental Health:

When children sleep well, parents can sleep well too.

  • Reduced Stress for Parents:

Sleep can reduce stress in parents and make them more patient.

  • Improved Family Dynamics:

Sleep can improve family dynamics as children sleep more consistently.

What Are the Risks or Drawbacks of Cry-It-Out?

Although CIO has its advantages, it also comes with concerns.

First of all, let’s talk about that pain in your heart. It can get quite irritating. Many parents feel guilty or anxious about that, which is completely normal.

And then consider the possibility that the CIO may not necessarily work well with your baby. For example, if your baby has been classified as highly sensitive, they may not do too well with this procedure. And if your baby suffers from separation anxiety, they might need something a little less harsh.

Moreover, let’s also remind ourselves that inconsistent use can create problems too. If you are inconsistent, your baby may end up getting mixed messages, resulting in more crying, and believe me, that defeats the whole purpose here.

What Are the Alternatives to the Cry-It-Out Method?

If the CIO method does not appeal to you, fear not; there are definitely other approaches to consider.

  • Fading Method:

Parents gradually become less involved in putting their children to bed. This is about gradually getting your child accustomed to sleeping by themselves.

  • Chair Method:

The approach works by sitting in a chair right next to the baby’s crib while they fall asleep. However, you don’t pick up the baby in this case. Each night, you move the chair a little farther from the baby’s crib. Eventually, the baby learns how to fall asleep on their own while still aware of your presence. The approach helps a baby sleep on their own.

  • Bedtime Routine Adjustments:

Occasionally, simple changes to bedtime rituals can make a significant difference. A not-so-simple adjustment may help reduce those pesky nighttime wakings.

  • Responsive Sleep Training:

This method is all about balance. The parents will respond to crying outbursts but also teach the child to fall asleep independently.

Conclusion

Cry-it-out is a technique that can help babies sleep on their own if applied at the correct age. But CIO is not the only approach to children’s sleep. Sometimes, it is not the best technique to use. The best approach is the one that makes the baby feel comfortable and healthy for the family. If a parent is experiencing difficulty getting the baby to sleep, then consulting a child health specialist is appropriate.
