As summer ends and children trade flip flops for school shoes, Mariella Frostrup starts the new academic year exploring what can affect a child's IQ.
Parents who read to their children, talk at the dinner table and help with homework might have happy offspring, but will they be making them smarter?
In the light of research into the influence of genes, Mariella and her guests debate the role of parenting on intelligence. They explore recent research into the effect of exercise and sleep and ask what difference can breastfeeding, flashcards, violin lessons and superfoods really make.
For the first in a new series of Radio 4's parenting programme, Mariella is joined by Dr Stuart Richie, Postdoctoral Fellow in Cognitive Ageing at the University of Edinburgh, writer and consultant Sue Palmer, Dr Sophie von Stumm, Lecturer in Psychology at Goldsmiths and Director of their Hungry Mind Lab, and Hilary Wilce, writer, advice columnist and coach.
