The son of Rohan Wray, 22, and Chana Al-Alas, 19, of London was found with bone fractures across his body, leading to their arrest on suspicion of abusing their son. However, it was later discovered that the fractures were caused by severe rickets.

The boy died after severe skull fractures led to brain damage.

Mr Wray and Miss Al-Alas place blame squarely with Great Ormond Street and University College hospitals, who failed to diagnose the disease.

Mr Wray told the BBC, "I really feel that they didn't really know what they were doing and they just pre-judged us way too early.

"I said apart from him rolling over in his cot and hitting his head on the side of the bars I can't think of any other explanation because we haven't dropped him, nothing's dropped on him. The look from them was that simply they didn't believe my explanation."

University College hospital has defended their levels of care in a statement saying, "We regret that we were unable to reverse his deteriorating condition despite our intensive efforts in the short time he stayed with us. We would like to offer our sincere condolences to Jayden's parents.”

They added that they believe they acted with “Jayden's interests at heart".

Criminal charges against the couple were dropped in December, but the local authority brought civil charges against the pair. Family court judge Mrs Justice Theis criticised the two hospitals, calling the care as “sub-optimal”.
