A nightmare neighbour who ruined a disabled mum's eyesight in a horrific attack "stabbed her sister" in a previous offence.
Lian Clayton was jailed at Liverpool Crown Court after she repeatedly punched the disabled woman in her 50s on her own doorstep.
The 25-year-old pinned the woman to the floor as she punched her before beginning to kick her and stamp on her ribcage.
A neighbour who had rushed to the woman's aid said she "heard the sounds of bones crunching" as the woman was "screaming in pain".
The court heard Clayton had "stabbed her sister" and was convicted of wounding in 2010.
The case was heard before a youth court, as Clayton was 14 at the time, and she received a youth referral order for the attack, although no further detail was given in open court.
Zahra Baqri, prosecuting, said Clayton had four previous convictions for five offences in total.
Speaking about the attack on her neighbour, Ms Baqri said there was "some background" between the neighbours, who had lived a few doors away from each other in St Helens.
Clayton had previously confronted Karren Bradshaw and after receiving a message from the woman's daughter, telling her to leave her mum alone, Clayton appeared at Mrs Bradshaw's door and said "where's that fat b******" about her daughter.
When Mrs Bradshaw explained she didn't live with her daughter Lian "punched her to the face a number of times" then "dragged her out of her own home whilst still punching her".

She said: "The victim lost consciousness and when she came to she was on the ground.
"At that point the victim was screaming for help."
Julia Boyd, another neighbour, heard the woman's screams and ran to the scene, where she was confronted by Lian "sat straggling over" the woman having "pinned her arms down with her knee" while punching and screaming at her victim.
Mary Clayton, Lian's mother, was "shouting at her daughter to get off the victim".
Ms Baqri said: "The neighbour tried to help but was unable to do so. All she could manage was to hold the victim's hand to try and comfort her.
"Lian Clayton proceeded to stamp on Mrs Bradshaw's ribcage with her foot."
The neighbour managed to get Mrs Bradshaw to stand and she was then taken to hospital having suffered a broken nose, extensive bruising to her face and damage to her eye which has resulted in her eyesight being ruined and her seeing "spider legs" across her field of vision.
In an interview Lian Clayton claimed she was acting in "self defence" but later admitted assault causing actual bodily harm.
Mrs Bradshaw said she had been left "frightened" and was attacked "for no reason whatsoever".
Three months later mum and daughter Mary and Lian Clayton burgled Mrs Boyd and her husband, relying on his kind-hearted nature to carry out their crime.
While Mrs Boyd was in hospital "receiving treatment for a fall" Lian and Mary went to Mr Boyd's home and asked for help claiming they had locked themselves out.
He fetched ladders to help them and noticed their backdoor was open but "didn't think anything of it".
After returning from visiting his wife in hospital Mr Boyd discovered his wife's prescription medication, including morphine, house keys, car keys and food missing from his home.
He then watched CCTV footage he had installed, because of "recent problems with the Claytons", and saw the pair use the ladders and Mary climb into his bedroom window.
Nick Cockrell, defending, asked the judge to consider Clayton mental health issues and the current impact of coronavirus in prisons.
Mr Cockrell said reports showed Lian had experienced "quite a sad background in terms of her childhood and what is still quite a relatively young life".
He referred to other circumstances adding there was "an awful lot going on in Ms Clayton's life in the last few years" but did not disclose further detail in open court.

Mr Cockrell explained Lian had spoken with a doctor for a psychiatric report and had been "willing to assist and engage in that process".
The court heard he had been diagnosed with severe emotionally unstable personality disorder and "severe complex PTSD", both of which a doctor had found "contributed towards her behaviour in terms of the assault".
The judge, Recorder Robert Lazarus, explained this meant she "wouldn't have been capable of forming the necessary intent" and took the diagnoses into account when sentencing Lian Clayton.
Recorder Lazarus went on to explain Lian was "essentially homeless".
He said that if he was to impose a community or suspended sentence Lian "simply wouldn't receive the treatment she needs", although she would receive this help from authorities when released on licence as part of a custodial sentence.
Lian Clayton was jailed for 10 months and three weeks for assault and burglary.
Mary Clayton, sentenced at an earlier hearing, was handed an eight month sentence suspended for 18 months for burglary and assaulting an emergency worker in a separate incident.
A two year restraining order preventing the Claytons from contacting Mr and Mrs Boyd and an indefinite restraining order preventing them from contacting Mrs Bradshaw were imposed.
