"During this time we lay the foundations and building blocks for life.
"And it is when we learn to understand ourselves, understand others and understand the world in which we live.
"This is why it is essential, to not only understand the unique importance of our earliest years, but to know what we can all do to help raise future generations of happy, healthy adults."

It will go on to "explore in more depth the importance of a child's social and emotional world" and the significance of relationships and "surroundings and experiences".
She added: "And of course, by understanding our own childhoods – what has shaped our own beliefs, relationships, behaviours and feelings – we, as adults, are better placed to play our part in positively shaping future generations."
