Jonathan Chester and Patrick Regan's 'My Unflappable Mum' is a loving tribute to 'the most rare of birds - the incredible, unflappable mum'. Chester's striking and intimate nature photographs of tuxedoed penguins and their young beautifully illustrate Regan's charming verse that honours those incredible, unflappable mums who nurture and instil a spirit of adventure and independence in their young.
