Pediatricians commonly are asked to see infants presenting with symptoms of colic. The frequent and intense crying associated with colic is understandably quite distressing to parents, who often worry about a serious underlying medical cause. There also is the stress of trying to soothe an irritable infant who often does not seem to respond to the typical interventions.
Conventional wisdom about colic has been that the behaviors are the result of some gastrointestinal problem that, while not perfectly understood, tends to be mercifully self-limited and not predictive of future medical or mental health problems. This perspective then leads to pediatricians typically offering mainly sympathy and reassurance at these visits.
A new study,1 however, challenges some of this traditional thinking. The data come from a remarkable longitudinal study called the Generation R Study (R being Rotterdam in the Netherlands) that has prospectively studied a group of nearly 5,000 children from before birth into adolescence. Colic symptoms were briefly assessed when infants were about 3 months old and emotional-behavioral problems have been prospectively measured at multiple time points subsequently using well-validated rating scales.
The main finding of the study was and, to a lesser extent, in adolescence. This held for both internalizing problems (like anxiety and depressive symptoms) and externalizing problems (like defiance and aggressive behavior). At age 10, participants also underwent an MRI scan and those who were excessive criers as infants were found to have a smaller amygdala, a region known for being important in regulating emotions.
The authors concluded that colicky behavior in infancy may reflect some underlying temperamental vulnerabilities and may have more predictive value than previously thought. The connection between excessive crying and a measurable brain region difference later in life is also interesting, although these kinds of brain imaging findings have been notoriously difficult to interpret clinically.
Overall, this is a solid study that deserves to be considered. Colic may reflect a bit more than most of us have been taught and shouldn’t necessarily be “shrugged off,” as the authors state in their discussion.
At the same time, however, it is important not to overinterpret the findings. The magnitude of the effects were on the small side (about 0.2 of a standard deviation) and most children with excessive crying in early infancy did not manifest high levels of mental health problems later in life. The mothers of high crying infants also had slightly higher levels of mental health problems themselves so there could be other mechanisms at work here, such as genetic differences between the two groups.
So how could a pediatrician best use this new information without taking things too far? Regardless of the question of whether the excessive crying infancy is a true risk factor for later behavior problems (in the causal sense) or whether it represents more of a marker for something else, its presence so early in life offers an opportunity. Primary care clinicians would still likely want to provide the reassurance that has typically been given in these visits but perhaps with the caveat that some of these kids go on to struggle a bit more with mental health and that they might benefit from some additional support. We are not talking about prophylactic medications here, but something like additional parenting skills. Especially if you, as the pediatrician, suspect that the parents might benefit from expanding their parenting toolkit already, here is a nice opportunity to invite them to learn some new approaches and skills — framed in a way that focuses on the temperament of the child rather than any “deficits” you perceive in the parents. Some parents may be more receptive and less defensive to the idea of participating in parent training under the framework that they are doing this because they have a temperamentally more challenging child (rather than feeling that they are deficient in basic parenting skills).
It’s always a good idea to know about what resources are available in the community when it comes to teaching parenting skills. In addition to scientifically supported books and podcasts, there has been a steady increase in reliable websites, apps, and other digital platforms related to parenting, as well as standard in-person groups and classes. This could also be a great use of an integrated behavioral health professional for practices fortunate enough to have one.
In summary, there is some new evidence that colic can represent a little more than “just gas,” and while we shouldn’t take this one study to the extreme, there may be some good opportunities here to discuss and support good parenting practices in general.
