I respect your intent —- there’s a lot going on in the co-enjoyment of reading that can’t be captured by research. But what research has captured are differences in literacy, verbal and cognitive abilities in children from different socioeconomic classes. When researchers went in and studied the actual reading styles of the different parents, they found that higher socioeconomic status parents asked different types of questions and engaged in different thinking patterns than lower SES parents. There was a tendency towards abstraction in the former and concreteness in the latter. That kind of stuff has significant effects in the process of early childhood brain development, which people don’t realize is this crazy critical window that the brain kind of solidifies around for the rest of life. So yeah, read and enjoy it, but be mindful of staying engaged and of engaging your kids’ thinking in multiple areas. Sometimes that’s not exactly natural or “in the moment.”
