If your baby has been given the colic label, here is what you actually need to know.

If you have a newborn or baby who cries a lot, you have probably heard the word colic. It may have come from a GP, a maternal health nurse, a family member, or something you read online. And it may have felt like, "Thank goodness! Now we know what it is!" Like finally someone had a name for what was happening.

But here is what is important to understand: colic is not a diagnosis. It is not the name of an illness or a condition. It is a label that describes frequent, unexplained crying in an otherwise healthy baby. The key word there is unexplained. Colic does not tell you why your baby is crying. It tells you that nobody has found out why yet.

Where the term comes from

The most commonly used definition of colic comes from what is known as the rule of threes: crying for more than three hours a day, more than three days a week, for more than three weeks. It is a description of a pattern, not an explanation of a cause. And importantly, this definition was developed decades ago and there has been significant debate about it in the clinical literature ever since.

The term continues to be used perhaps because it can help sometimes to have a shared language or name for a difficult experience. But the challenge is that it can also end up as a full stop rather than a continued conversation that should keep going.

"It is colic" is not the end of the conversation

When a baby cries frequently and the answer is "it's colic," what that really means is that a clear cause has not been found. That is not the same as there being no cause. And for many babies who are given the colic label, there is something underlying that is worth looking into.

Reflux and silent reflux, oral function challenges, feeding difficulties, food sensitivities or intolerances, gut immaturity, muscle tension from birth,these are just some of the things that can contribute to a baby who cries frequently and is clearly uncomfortable. None of these are captured by the colic definition. None of them are ruled out by it either.

I want to be upfront here. I am a sleep consultant, not a healthcare practitioner, and I am not in a position to assess or diagnose what might be going on for your baby. But what I can say with confidence is that if your baby is crying a lot and the answer you have been given is colic, it is worth continuing to ask questions. You are not being difficult or anxious. You are advocating for your baby. Those are very different things.

What is actually worth doing

Start with your GP or paediatrician and describe what you are observing as specifically as you can. When does the crying happen? How long does it last? What seems to trigger it or help settle it? How is feeding going? Does your baby seem to be in pain or discomfort? The more detail you can give, the more useful the conversation tends to be.

If you feel like your concerns are being brushed off with "it's just colic, they'll grow out of it," it is completely reasonable to seek another opinion or ask for a referral. An IBCLC can be invaluable if feeding is part of the picture. A paediatric osteopath or physiotherapist may be helpful if there are signs of physical tension or discomfort. Your gut feeling that something is not quite right is worth taking seriously.

It is also true that colic does tend to resolve, usually around three to four months. But resolving is not the same as the underlying cause being found and addressed. Sometimes things simply improve as a baby's system matures. That does not mean they could not have benefited from support along the way.

What does this have to do with sleep?

A baby who is uncomfortable, in pain, or unsettled for any of the above reasons will often not sleep well either. And that makes complete sense. But this is not a sleep problem in the way it is sometimes framed. It is a symptom of something else going on.

If your baby is crying a lot and sleeping poorly, and colic has been the answer offered, I would gently encourage you to focus on the underlying picture first before jumping to sleep strategies. Settling and sleep often become much more manageable once the piece that has been driving the distress is properly understood and supported.

Trust what you are noticing

Hearing "it's colic" when you are exhausted and watching your baby in distress is genuinely hard. It can feel like the door closing on any real answer. But it does not have to be.

Trust what you are noticing. A baby who is frequently distressed is telling you something, and you are the person best placed to observe and advocate for them. Finding practitioners who are willing to look at the whole picture, to explore the sum of all the parts rather than viewing each thing in isolation, can make all the difference. That kind of integrative, curious approach is often where real answers start to emerge.
