A woman who allowed the death of her two-year-old son at the hands of her murdering boyfriend has been jailed for four years
She was convicted last month in a trial at Manchester Crown Court of allowing his death after the court heard she knew her son had received two nasty injuries to his backside and head the day before when Rigby was looking after him.
Smedley who has already been pregnant seven times was castigated by the judge for having 'an irresponsible view of obligations of a mother' after he heard how she put her love life first.
Sentencing her, Mr Justice MacKay said the juryís verdict meant they were sure she knew or ought to have known there was a significant risk of serious harm to her son.
He told Smedley: 'At no stage did you do anything to protect Rio from his fate. He must have suffered greatly before his death.
'You should never have left him that night. It was quite clear that Rio was at risk. You were infatuated with Rigby at the time and I think you still are, or at least during the trial.
'At the top of your list was a need to please him (Rigby).'
The mother of two had been headbutted, slapped across the face and called a 'fat slag' by 23-year Rigby during a stormy relationship.
Yet even though he was arrested and banned from contacting her she was so infatuated she dropped charges against him - even though her son Rio had had previous unexplained bruises.
The judge noted that she had shown no remorse over Rioís death and the only time she showed distress was when her 999 call to the emergency services was played in court.
The tragedy occurred whilst Smedley was heavily pregnant with a third child - but had not told Rigby someone else was the father.
She only revealed the truth in a witness box when she was testifying at a trial over the toddlerís death.
Whilst awaiting trial she fell pregnant again to a neighbour but she had a termination in prison two weeks ago - and is now considering sterilisation, (halle-fucking-lujah!)
the judge was told.
Mr Justice MacKay told Smedley, who will be released on licence halfway through her sentence
: 'I hope you will take the assistance that the prison will give you.
Her two surviving children will now be cared for by foster carers and she has made little effort to contact them.
Smedley began dating Rigby, who has previous for or assault, public order matters and car theft, in 2011.
Last January she announced she was three months pregnant with her second child but Rigby punched and slapping Smedley in the belief she had been texting other men.
Friends recalled how he also headbutted her and kicked her in the head during a row in the kitchen whilst waiting for her to 'get him some money'.
Last March 21 when Smedley was five months pregnant, Rigby punched her in the face grabbed her by the cheeks, pushed her into a door and headbutted her after claiming she was planning to have sex with other men.
He immediately returned to their home and that evening Smedley left him to care for Rio for an hour whilst she and a friend went off to pick up portions of fish chips from a nearby takeaway.
When Smedley returned home Rio already had red blotches on him and was feeling sick but she ignored the warning signs and instead went out again the next day
to see relatives leaving the youngster at home with her violent boyfriend.
When she returned the youngster was sporting a bruise to his bottom, yet the following day the mother went out for a third time leaving Rio with Rigby
She was eventually called in a text by Rigby who said Rio had fallen down the stairs. She rushed back home to find the youngster was not moving and his eyes ďsunkĒ to the back of his head and dialled 999.
Rio was taken to the Royal Bolton Hospital but later died of a ruptured liver caused by punches kicks and stamping.
A pathologist who examined Rio, found 91 separate marks of injury including 40 bruises and abrasions to his head and face, 11 bruises and abrasions to his abdomen, a 9.5cm x 3.7cm bruise to his buttock, seven bruises and abrasions to both his arms, and 20 injuries to his legs and feet.
