Kate Middleton has expanded her early years initiative to include business leaders and commerce.

The Financial Times published her op-ed on social and emotional development in children's first five years.

The well-being of parents is the "biggest single factor" in determining a child's well-being, Middleton said.

She launched her new Business Taskforce for Early Childhood this month.

The task force seeks to foster social and emotional well-being in the workplace and in young children.

The task force will look at opportunities to put early years at the heart of delivering the "social" element.

Middleton's Shaping Us campaign aims to raise public awareness of the importance of a child's first five years of life.

The campaign aims to make the scientifically intriguing subject one of the most strategic in our time.
