What do we know?
- By crying, babies can express their pain, hunger, anger and boredom but sometimes they cry for no specific reason.
- Even healthy babies who get excellent care cry a lot.
- In the first 3 months of life, around 25% of babies cry for more than 3 and a half hour each day.
- At around 3 months old, babies start to cry less.They begin to babble and to move more easily, and start to be able to express themselves in ways other than crying.
- Persistent crying that seems to have no reason can make parents feel worried, upset or out of control.
- All babies go through times where their crying is excessive, unexpected and inconsolable, but those who experience this a lot (about 10 to 20%) are sometimes called “colicky” infants.
- The most common sign that a baby might have colic is if he cries for more than 3 hours per day, at least 3 days a week, for 3 weeks in a row.
- There are 5 specific characteristics of normal excessive crying or infant colic:
- The crying is often unexpected, unpredictable and inconsolable (not related to hunger or wet diapers);
- It often starts at the end of the afternoon or in the evening;
- It can last 35-40 minutes, or even as much as 2 hours;
- It increases as the weeks go by, is most intense when the baby is about 2 months and then decreases until about the age of 5 months;
- The baby seems to be suffering.
- Excessive crying that continues after the colicky period (past the 4th or 5th month) is often associated with a difficult temperament (agitated baby, hard to calm down).
- These characteristics can make the parent feel powerless, discouraged or incompetent. It can create problems for the parent-child relationship, because the parent may become less involved and be less comforting with the child.
Paying attention to...
- the reasons behind the crying (such as hunger, physical discomfort, fear).
- crying that cannot be explained.
- the anger that inconsolable crying can provoke in a parent.
- abnormal, high-pitched sounds that are irritating to hear, especially if they are frequent and still happening at the age of 5 months.
What can be done?
- Respond quickly and calmly to the need that the baby is expressing.
- Hold the baby close to your body as often as possible and watch to see if the crying calms down.
- If it becomes frustrating to respond the baby’s needs when he won’t stop crying, pull away and calm down before going back to the baby.
- Ask someone else to take over if you are not able to calm down.
- Respond quickly to the crying to try to comfort the baby, even if it’s difficult to bear (cuddle him, take the baby in your arms, speak softly).
- Ask for help if you need it.
