According to Megan Gunnar, who specializes in the intersection of developmental psychology and neuroscience, a good early childhood caregiver “requires [the] capacity to analyze what’s happening in the moment” and determine what concept – whether a numerical concept, or one related to language or physics – the child could be learning. Responding “in the moment, dynamically, really takes analytic skills, executive function, ordering and sequencing, and knowing a lot of information.”
