Infant Development and Preterm Care

The vast majority of women (60–90%) hold infants on their left side. Such a population-level lateral bias has been shown to improve the processing of socio-emotional stimuli in both the woman and the baby. Recently, some studies related cradling lateralization and Autism Spectrum Disorders (which entail socio-communicative deficits and a reduction of the typical lateralization of brain functions), raising the possibility that the asymmetrical cradling behavior experienced during infanthood might be related to the infant's neurodevelopment. Any progress made towards earlier diagnoses could significantly increase the chance of successful intervention for these patients. We here suggest that a wide retrospective investigation on family photo albums and home movies of children diagnosed with Autism might provide useful data about early behavioral signs of this condition. We hypothesize that an atypical trajectory in maternal cradling might be one of the early signs of interference in dyadic socio-emotional communication, and thus of potential neurodevelopmental dysfunctions.
