Kate Middleton is campaigning for the importance of the first years of life.

She visited Leeds Kirkgate Market to discuss childhood development.

One man asked for a selfie with her, and she was friendly and gracious.

Leeds has a personal connection to Kate through her family history.

She toured the market stalls, chatting with vendors and trainee teachers.

Kate also met with students at the University of Leeds who study childhood development.

The campaign, Shaping Us, raises awareness and encourages conversation.

Kate is credible to lead the campaign as she is a mother of three.

The campaign is important because children's early experiences shape their development.
