Sumaiyyah Wakil became an ISIS bride aged 16 when she left her Hampshire home and travelled to Syria in August 2014.
The teenager left her family a handwritten letter begging them not to alert the police to her journey.
Now aged 21 and with a two-year-old child, her family are desperate for her to return to Britain for the safety of her daughter.
She travelled to the war-torn country to help those suffering during the fighting and expressed ‘anger’ about ‘the state of the Islamic community’, a court heard last month.
Flying on her own to Bulgaria, she then on to Turkey, using money stolen from a fund for her eldest sister’s wedding.

Within weeks of her arrival, she got married, had a miscarriage and became a widow, before marrying a second man who fathered her daughter, Zaynab.
Her brother, Salim Wakil, was found guilty of funding terrorism at the Old Bailey on last month, by wiring her £2,350.
The court heard his sister wanted to die as a martyr as she made her way to ISIS-controlled areas.
Sumaiyyah left a series of voice messages for relatives from Raqqa telling them how great life was and that she was not coming back.

She even sent pictures of her daughter with a drip in her hand to her brother in May 2017 to try and persuade him to send more money.
Her messages sent via WhatsApp and encryption service, Telegram, also included photos of the River Euphrates, near where she was living in Syria.
Sumaiyyah also told her other brother, Shamim, via text message she did not want to come back to the UK and that her husband in Syria burned her passport.
In one voice in May 2015, she described a stoning as ‘cool’.
She said: ‘Guess what today there’s going to be a stoning of a woman. Me and my husband are going to go and see it inshallah. So cool man.’
A family member of Sumaiyyah told the Sunday Times the youngster began wearing a headscarf aged 14 and may have been a victim of racist attacks when she was beaten up at school.
Unlike fellow ISIS bride, Shamima Begum – who travelled to Syria with two friends aged 15 – Sumaiyyah has reportedly been stripped of her British citizenship.

In messages to her brother, Sumaiyyah said she was scared and feared if she did not have enough money to escape Syria and pay smugglers she would be captured by Bashar al-Assad’s forces
Her family are said to be appealing against the decision with the Home Office and the status of her daughter, who was born in Syria, is unclear.
A close relative urged of Sumaiyyah begged her to come back, telling the Sunday Times: ‘If there’s any way you can get out, please just come back – for your daughter’s sake.
‘We all miss you. We would really like to see you again.’
Her family added in a statement: ‘We pray that, whatever she may or may not have done, she and our granddaughter are safe.’
She is understood top have married Muhammad Mehdi Hassan, 19, who was killed along with fellow Portsmouth jihadist, and Mamunur Mohammed Roshid, 24, in October 2015.
After her first husband’s death, Sumaiyyah suffered a miscarriage and then married a Canadian jihadist and is holed up in the besieged town of Baghouz, where US-Syrian forces are clearing ISIS from their few remaining strongholds.
Shamima Begum, 19, is pleading with the government to allow her back into the country, with her family saying that they would raise her child
Salim Wakil denied funding terrorism but was convicted by a jury and was sentenced to 30 months in prison on February 8.
The pleas of Sumaiyyah’s family come just days after Shamima Begum, who is nine months pregnant, begged to be allowed to come back to the UK to have her baby.
Yesterday her relatives asked the British government to give them custody of her unborn child if she is allowed to return to the country and given jailed.
Ms Begum was one of three Bethnal Green Academy schoolgirls in east London, who joined the terrorist group four years ago.
The government has indicated it will not allow her to return but her family said they would now be consulting a lawyer.
