A ‘china doll’ five-year-old who has suffered 90 broken bones in her short lifetime overcame her disease to go wakeboarding with her dad. Hadley Larson, five, has osteogenesis imperfecta - also known as Brittle Bone Disease - and has been in and out of hospital since she was born in 2012. A lack of the protein collagen means Hadley's bones are so brittle they can shatter in an instant, and a light fall can leave her with serious injuries. So mom Kendra Larsen, 36, says she was stunned when Hadley asked her if she could try to surf with dad Eric Larsen, 38, on a day trip to Ririe Reservoir, Idaho, on July 21.
