The model posted an adorable snapshot which showed the tiny tot lying on blue and white striped fabric. Coco looked to the side as she held onto her mum's hand, her big blue eyes focused on something in the distance.
She appeared to be in the shade, but it looked like a gorgeous sunny day in Turkey, where the Keating clan is enjoying an end-of-summer break. Storm captioned the picture: "My little beach babe [blue heart emoji] #cocoknoxkeating."

Storm and her husband, former Boyzone singer Ronan, are also doting parents to their three-year-old son, Cooper, and the Irishman shares three other children with his ex-wife, Yvonne Connolly: Jack, 21, Missy, 19, and Ali, 14.
Little Coco is just five months old, having been born at the end of March amid lockdown in the UK. At the time, Ronan shared a post to Instagram announcing the happy news.
It read: "Hello world. Spreading some good cheer at this time with the announcement of the safe delivery of our little girl Coco Knox Keating. Calmly arrived on 27/3/20.
"Mama & Baba are rocking #HappyTimes #KeatingClan #BabyKeating." The dad-of-five and his wife had further reason to celebrate during their holiday, as 18 August marked their wedding anniversary. The couple tied the knot in Istanbul five years ago.
