The mother of the child victim of paedophile Craig Sweeney said she was "gut-wrenchingly sick" over a decision not to refer his sentence to the Court of Appeal.
The Attorney General said he would not challenge the minimum sentence handed down to Sweeney by a court last month. Paedophile Sweeney (24) was sentenced to life but can apply for parole after five years and 108 days.
A statement on behalf of the three-year-old victim's mother, of Cardiff, south Wales, was released by her solicitor.
She said: "We are gutwrenchingly sick at today's announcement.
"This case is too horrific to know the details, but we can tell you that Sweeney was literally found with our child's blood on his hands.
"This really started because a convicted paedophile was released too soon from prison.
"If the likes of him, who pose such a high risk to children, are let out too soon again, this will happen again and again.
"When it does, the politicians and everyone else involved here will also have blood on their hands.
"We are sad that instead of working together to protect children, some politicians and members of judiciary have used our child's tragedy to score 'who's the boss' points.
"Whoever wins this battle, our children lose. This has been a terrible blow to us and we would respectfully ask that we be left alone to take in all that has happened and allow us time to brace ourselves for what may also turn out to be another terrible blow when the IPCC report into this case - due to be published any time now - is released."
