Nine out of ten people are right-handed. Despite this fact, why do most women hold their babies on their left side? It is usually because holding the baby on the left side frees up the dominant hand in order for the mom to be able to multitask. But if that’s the case, then why do left-handed women still hold babies on their left side? Turns out handedness has nothing to do with cradling.
The question of why women default to their left side when cradling an infant has puzzled evolutionary and developmental psychologists for decades. But a new study appearing in the journal Evolutionary Psychology may bring us one step closer to the answer.
A team of psychologists at the University G. d’Annunzio of Chieti–Pescara in Italy designed an experiment to test whether women who cradled their baby on their left side were more likely to display a secure attachment style. Remember that attachment styles come in two forms — secure and insecure. People with secure attachment styles have an easier time establishing and maintaining constructive, close relationships (most likely because they experienced healthy and stable interpersonal relationships growing up). People with insecure attachment styles, on the other hand, find it difficult to maintain healthy interpersonal connections.
