Hi, I'm Federica — sleep consultant and founder of With Love Coaching 🌷
The Cry-It-Out (CIO) method is among the most debated approaches to help children fall asleep independently.
Scientific research offers valuable data, but the best choice always depends on who you are as a family, your child's temperament, and how the method is applied in daily life.

In my work, with the With Love Method, I transform scientific evidence into practical and gentle strategies, because science is only valuable when it translates into concrete care.

What is CIO and its variants

The Cry-It-Out method involves letting the child cry for a predetermined time, with the aim of promoting their ability to calm down and fall asleep on their own.

There are two main versions:

🔹 Full extinction

The child is put to bed awake and is not checked on until the morning.
👉 I do not recommend it: it is an approach too harsh and inconsistent with what we now know about emotional development and attachment.

🔹 Graduated extinction (Ferber Method)

This involves brief checks at increasing intervals (e.g., 3–5–10 minutes), during which the parent can reassure the child with their voice or touch, without picking them up.

👉 What I propose in my programs, however, is a gradual, responsive, and respectful approach, where the parent remains present and progressively reduces support, without ever leaving the child alone to cry.

Is it safe? What the literature shows

Over the years, CIO has been the subject of numerous studies.
Research shows conflicting results, but useful for understanding when and for whom it can work — and when it is better to choose gentler paths.

🩵 Studies that support CIO (if applied correctly)

• Attachment and development: occasional use of CIO does not compromise attachment security at 18 months (Bilgin et al., 2020).

• Fewer sleep difficulties: over time, fewer awakenings and less crying are observed (Giesbrecht et al., 2020).

• Reduction in crying: after a few nights, total crying decreases (Rickert & Johnson, 1988).

• Acute vs. chronic stress: distinction between initial crying and chronic stress, with no evidence of long-term harm (Mindell et al., 2006).

• Benefits for parents: improved sleep and well-being, reduced anxiety and symptoms of postpartum depression (Moore, Meltzer & Mindell, 2008).

🧡 Criticisms and cautions raised by research

• Attachment and regulation: some studies highlight a possible underestimation of emotional effects (Davis et al., 2021).

• Unconsoled crying: prolonged crying can increase stress levels (Bell & Ainsworth, 1972).

• What the child "learns": risk that the child does not learn to self-soothe, but only to "get used to" the lack of response (Rosier et al., 2020).

• Cortisol: prolonged stress can elevate the release of cortisol, the stress hormone (Douglas & Hill, 2013).

• Emotional impact on parents: many find it difficult to tolerate prolonged crying (Cleveland Clinic, 2021).

Summary of the evidence

Science tells us that:

• CIO is not intrinsically harmful if applied correctly and in a calm environment;

• it is not suitable for all children, nor for all parents;

• gentle alternatives exist, equally effective and more emotionally sustainable.

My professional stance 🌷

As a sleep consultant, I rely on studies but always put the child and the relationship at the center.
With the With Love Method:

💫 I avoid full extinction;
💫 I promote consistency and respect for developmental timelines;
💫 I guide parents to gradually reduce support, always maintaining presence and emotional connection.

The goal is not to "teach how to sleep", but to guide the child towards autonomy with confidence and security.

Making the right choice for your family

If you are considering CIO as a sleep training method, I invite you to ask yourself some questions:

🌙 Can I be consistent for at least one week?
🌙 Does my child respond better to small steps or clear changes?
🌙 How much crying can I emotionally tolerate?

If the answer is “not much”, perhaps the gentler path is also the most suitable for you.

Age and application windows

• 0–4 months: no CIO. At this stage, contact, frequent feedings, and prompt response are needed.

• 3 months: still too early. Circadian rhythms are forming, crying is communication.

• 4–5 months: you can start gentle shaping (routine, drowsy-but-awake, presence), but not full CIO.

• ≥ 6 months: some children are more ready to consolidate sleep, but I always assess temperament, history, and nutritional needs.

During sleep regressions (4, 8, 12 months) CIO is not recommended: the child needs comfort and stability, not detachment.

How long can you let them cry?

• Ferber method (graduated): brief checks at progressive intervals (5–10–15 minutes), without picking them up.

• Full extinction: no checks — not recommended.

If crying lasts longer than 90 minutes, it is important to stop and re-evaluate: it may not be the right approach for your child.

Naps and Cry-It-Out

Daytime naps are more difficult to manage with CIO because the sleep pressure is lower.

• Use shorter check-in intervals.

• If crying exceeds 30 minutes, stop and re-evaluate: wake times, routine, or environment.

• If it doesn't work after a few days, switch to a more responsive method, such as the chair method or a short version of the Sleep Lady Shuffle.

Safety and ethics

Prolonged, unconsoled crying can be stressful for everyone.
Every decision must consider the age, temperament, sleep history, and emotional well-being of the family.

The goal is not "performance," but autonomy through connection.

Effectiveness and alternatives

CIO can work, but it is not the only way.
Controlled crying (Ferber) is not the same as full extinction, and a gentle approach can be just as effective.

With the With Love Method, I guide the child with presence, reassurance, and consistency, gradually reducing my intervention until they achieve sleep autonomy — always with respect and attentiveness.

Conclusion: science guides us, but listening directs us

Research can point a direction, but only listening to the child and the family makes the guidance truly human.
If CIO does not respect your limits or your little one's temperament, know that effective and gentle alternatives exist, based on evidence but rooted in relationship.

love teaches how to feel safe while learning it.
