"Love grows healthy brains."
That's the message from the Brainwaves Trust, which teaches secondary school students about the importance of providing a caring and nurturing environment for very young children.
Using educators who teach classes directly, the programme teaches students that it is vital for a child's healthy brain development to have loving relationships in the first few years of its life.
Educator Maria McKenzie said the aim of the programme was to help students make good choices around their relationships with children, whether that was their young siblings, cousins, other whanau members or, eventually, their own children.
Ms McKenzie said there were still many people who thought children had to be "toughened up" as young as possible, so they would grow up to be independent.
