Adjourning the case for a psychiatric report to be prepared, Judge Graham Neville said it was one of the worst he had ever seen.
Williams committed the offences at a flat in Exeter last summer, after drinking home-made lager, stout, cider and vodka.
Williams, who did not give evidence, told the police he was not responsible for injuries to the child and said she must have suffered them when she strained herself going to the lavatory.
After the case, Devon's director of social services, Andrew Williamson, expressed his horror at the offences: 'Social services staff inevitably encounter some of the most extreme examples of human behaviour, but this case had been distressing even for social workers experienced in child abuse investigations.
'The age of the little girl, and the severity of her injuries, marked this as a particularly disturbing case.'Reuse content
