Kate Middleton shows off her motherly side as she chats to London school pupils - Daily Mail

The Princess of Wales showed off her motherly side as she chatted with London school pupils about their teddy bears and birthday cakes in a new video promoting her Early Years campaign released today.

Dressed in a custom-made Burberry pussy-bow blouse and a pair of Spells of Love earrings, the royal mother of three was relaxed and chatty as she spoke to the children about their experiences growing up.

Earlier this week, Kate kicked off her new Shaping Us initiative, which she described as her 'life's work' with a glitzy reception at BAFTA in London, before she met with locals in Leeds to discuss the scheme yesterday.

The royal, 41, opted for a pair of £1,280 brown knee-high boots by Gianvito Rossi and a £950 midi cream dress from Victoria Beckham for her visit to discuss the importance of the early childhood years - which is the subject of her new campaign film.

To begin with, Kate toured Kirkgate Market - where she politely ignored a wolf whistle from a member of the public - and happily spoke with crowds of adoring royal fans who had waited to catch a glimpse of her.

The event was attended by newly appointed 'champions' from the world of music, science, sport, celebrity and academia including presenter Rochelle Humes, England women's football captain Leah Williamson and broadcaster Fearne Cotton.
