Two-year-old Isabelle Welsh suffered from weeks of abuse, which resulted in 21 broken bones, before she collapsed at home in Thornaby, Teesside, in September after suffering a "massive head injury".
The tot’s mother, 26-year-old Alexandra Walker and her 22-year-old boyfriend, Harrison Simpson, were convicted of murder and child cruelty this week following a trial at Teesside Crown Court.
Simpson was also convicted of sexually assaulting Isabelle, while Walker was cleared of that charge.
Now, it's been revealed that Simpson was charged with breaching a non-molestation order in March 2024 - some 18 months prior to the child's murder.

Cleveland Police said in a statement to Sky News: "A warrant for his arrest was issued that same month after he failed to appear at court.
"Multiple enquiries and arrest attempts were carried out to try to locate and arrest him but these proved unsuccessful."
Last week Simpson and Walker were jailed for life by Ms Justice Norton, with minimum terms of 28 years and six months for Simpson, and 22 years for Walker, both minus time spent on remand.
Isabelle’s father, Josh Welch, was in court for the sentencing, with the support of his family, as well as the nine female jurors who heard the case.
Ms Justice Norton thanked the jury for their work on such a “difficult” case.
According to Ms Justice Norton, the murder was the final act in a series of assaults which the pair attempted to cover up.
As Isabelle was dying, Walker delayed ringing 999 despite Googling “why would my toddler be bleeding” and she smoked a cigarette in her kitchen.
She first called her stepfather to come round, and it was only on his instruction that she finally alerted the emergency services.
When paramedics arrived within a minute, they found bruises all over the little girl’s body including to her head, neck, abdomen, back and private parts; there was blood in her nappy and sick on her face.
Isabelle was not breathing and was cold to the touch as medics battled in vain to save her, and she died the next day in hospital.
A post mortem revealed the extent of her injuries – that her skull was fractured, her brain damaged and that she had been sexually assaulted.
Experts told the jury that Isabelle had been shaken and her head impacted against a wall or the floor.
During her short relationship with Simpson, she voiced concerns that he might be a paedophile, and thought it was “weird” that he preferred to see her and Isabelle at the same time, rather than be alone with his girlfriend.
But Walker did not break up with him, even though she was suspicious enough to check if he was on the Sex Offenders’ Register.
Just 11 days before her fatal collapse, Isabelle was taken to her GP and then to hospital with a broken leg.
Despite misgivings of some staff, the little girl was discharged to her mother who had shown aggression towards medics when concerns were raised about what had happened.
Walker explained that Isabelle must have hurt her leg when it got caught in her cot.
On that occasion too, Walker had waited two weeks to seek medical help for Isabelle, despite the toddler being in pain and struggling to walk.
Richard Wright KC, prosecuting, told the court: “For weeks this child had been violently assaulted and her death, by that terrible head injury, was simply the end point in that campaign of violence to which she had been subjected.”
The prosecution said both defendants had ample opportunity to harm Isabelle and the abuse would have been obvious to anyone who lived in the two-bedroom house.
Videos taken last June – prior to Simpson coming into her life – showed the little girl happily playing, healthy and smiling.
The couple had met on Facebook Dating earlier last summer and Simpson became a regular visitor to the house where Walker and Isabelle lived together.
Walker had suffered from domestic violence previously and she had two cameras installed in her home, with one overlooking the back of the house that captured evidence reflected in a window.
The camera showed how Walker was a frequent drinker, sometimes downing up to 10 cans of Stella Artois, and Simpson was a habitual cannabis smoker.
The couple sold cannabis at times and Walker explained how bouts of self-harm which were caught on her CCTV were attempts to get out of selling drugs.
The CCTV footage also proved that Isabelle suffered a broken leg while in the sole care of Simpson.
Walker’s concerned mother said “looks like she is being abused” during one visit after Isabelle’s leg was broken.
Simpson also bathed Isabelle without Walker’s permission while he supposedly looked after the two-year-old when her mother attended a hospital appointment.
The night when Isabelle was fatally injured, the couple stayed up late, with Walker drinking cans of lager and Simpson smoking cannabis.
The next morning Simpson got up – claiming to be looking after Isabelle – while Walker stayed in bed.
In a horrific twist of fate one of the nurses who treated Isabelle’s broken leg – and who had concerns about her care – was on duty when she was brought back to University Hospital of North Tees, in a state of collapse 11 days later.
Simpson and Walker were arrested after Isabelle’s death.
Simpson declined to answer police questions and did not give evidence at the trial.
Walker gave various accounts of what happened, eventually telling police she now believed her boyfriend had been abusing her daughter.
Mr Wright said Walker did not protect her daughter, saying: “On the contrary, she delayed, she deflected, and she failed to act when action was most urgently required."
Outside court, Isabelle’s father Josh Welsh said justice had been done and that his daughter’s murderers deserved whole-life sentences.
Asked what she meant to him, Mr Welsh said: “My little girl… my whole life has been shattered, my whole family.“My sisters and brothers have lost their niece.
“It means the world to me that we have justice for Isabelle.”
Kirstie Devine, of the Crown Prosecution Service, said: “The prosecution presented a raft of evidence including pathology reports, expert medical evidence, CCTV from the home, records of text messages and phone conversations that showed only the two adults who were regularly with Isabelle could have harmed her.”
Senior Investigating Officer, Detective Chief Inspector Steve Chatterton of Cleveland Police, said: “Isabelle suffered catastrophic injuries at the hands of the very people who should have loved her, cared for her and protected her.
“Her life was cruelly taken in the most tragic and heart-breaking circumstances.”
