The mother of a Canterbury baby who died of catastrophic head injuries has denied any involvement in her son's death.

Soul Turany was less than four months old when he died in 2014.

No one has been charged over his death, but police have said either his mother, Storme Turany, or her then-partner, Tony Farmer, is responsible.

Coroner Ian Telford is examining the circumstances of Soul's death during a two-week inquest in the Coroners Court at Christchurch.

Turany gave evidence on Wednesday and denied ever having hurt Soul.

"Soul was everything to me - my kids are absolutely everything to me. Soul made me realise why I was put on this Earth and that was to be a mum," Turany told the inquest.

Turany told her lawyer Allister Davis she loved Soul "with everything I have".

Davis asked if she ever took her frustrations out on the boy: "Not once," Turany responded.

Had she ever injured Soul?…
