The 36-year-old, who has been remanded in custody since being charged last year, denies 24 sexual offences.
The charges he faces include raping a baby, sexually assaulting a baby and conspiring to rape a child.
He also has been accused of possessing, making and distributing indecent images of children.
His trial at Cardiff Crown Court is set to last around three weeks.
Two women, who cannot be named for legal reasons, also face sexual offence accusations as part of the case.
All three defendants face a total of 32 charges.
