A nursery worker has pleaded guilty to raping a toddler in his care and a string of offenses linked to the online grooming of more than 20 other girls.
Paul Anthony Wilson admitted two counts of oral rape of a girl aged two or three years old.
He also pleaded guilty to a further 45 charges of making and distributing indecent images and inciting youngsters to engage in sexual activity on the Internet.
The 20-year-old, of Newbold Croft, Nechells, Birmingham, was charged with rape in January after his arrest on suspicion of child abuse prompted an investigation into his employment at the nearby Little Stars Nursery.
Remanding Wilson in custody, Recorder of Birmingham Judge William Davis QC said: "The public have to be protected from you."
"It is almost inevitable that there will be what is called an indeterminate sentence."
