A man who raped a baby and sexually abused another girl has been jailed for 13 years at the High Court in Glasgow.
McKerrell will be supervised for 10 years on his release from jail
Iain McKerrell, 39, of Shortroods Road, Paisley, admitted repeatedly raping the baby between 2000 and 2004.
The court heard that the child may have been as young as 11 months old when McKerrell first raped her.
He also admitted systematic sexual abuse using lewd, indecent and libidinous practices towards another girl, aged 12, over four years.
Sentencing McKerrell, judge Lord Hardie said: "No right thinking person could imagine your actions."
He said that the baby's age when she was first raped was not known.
What was known was that the rapes occurred at a time when she was aged between 11 months and four years and six months.
Lord Hardie added: "On any view she was still a baby."
The judge placed McKerrell on the sex offenders' register for life.
He ordered him to serve 13 years in jail plus an extended sentence, which will see him serve a further 10 years on licence outside prison.
The baby's mother said: "He should be in jail for every one of these 23 years.
"The man is a monster. If I could murder him myself, I would. I hate him for what he's done and I hope he dies in jail."
During an earlier hearing, Lord Hardie heard how the girl's ordeal came to light when she revealed McKerrell had "done bad things" to her.
She is now said to be doing well at school.
The second victim's ordeal began when she was 12 and lasted four years.
McKerrell admitted using lewd, indecent, and libidinous practices towards her in houses in Erskine and Paisley.
After her sexual abuse came to light she was admitted to the psychiatric ward of Paisley's Royal Alexandra Hospital.
The girl was allocated a community psychiatric nurse after her release from hospital and is now at college being supported by a student counsellor.
