Prof Phil Fisher: 'the process of serve and return'

Professor Phil Fisher is an expert in children's neurobiological and psychological development. He was in NZ as the keynote speaker for a conference run by the Brainwave Trust. He says withholding feedback from babies can affect how their brains function. "The process of serve and return... where children serve as they look at the world around them and vocalise and adults return the serve by noticing what the child is doing and responding."
