But following her third child's birth last month, British officials stripped the 19-year-old of her citizenship as it is permitted to do in cases where it is "conducive to the public good".
Shadow home secretary Dianne Abbott blamed Javid's decision to remove Begum's citizenship for the child's death, accusing him of breaking global law. "The government will continue to do whatever we can to prevent people from being drawn into terrorism and traveling to unsafe conflict zones".
In earlier interviews, Begum said that while she did not agree with everything the terror group had done, she has "no regrets" about joining ISIS and suggested that air strikes against the terror group in Syria somehow "justified" the Manchester Arena terror attack.
And speaking shortly after the birth of her son, Jarrah, she told the BBC she wished her child to be British and to be raised in the UK.
Member of Parliament Diane Abbott of the Labour Party tweeted, "It is against global law to make someone stateless, and now an innocent child has died as a result of a British woman being stripped of her citizenship".

The Sunday Times says that Reema, 30, and Zara, 28, are living in separate refugee camps in Syria along with thousands of other families who have fled from territory formerly controlled by jihadis.
However, Javid had previously said that bringing the baby home from the war zone would be "incredibly hard".
Her family, who vowed to appeal against Mr Javid's decision, had also written to the Conservative minister, pleading with him to allow a safe passage for the boy to come to the UK.
She said: "Before the lives of more children are put at risk, these women should be brought back to Britain, face investigation for any crimes they have committed in Syria, and their children should be given the care and support they need. This is callous and inhumane", tweeted Abbott. The family said it planned to challenge Mr Javid's decision.
Last month he told British lawmakers: "Children should not suffer, so if a parent does lose their British citizenship it does not affect the rights of their child".
Shamima Begum's new born son has died in a displaced people's camp in northern Syria.
According to the BBC, the paramedic said the baby had been suffering from breathing difficulties and was taken to a doctor on Thursday morning. "I am willing to change", she said, following the revocation of her citizenship.
