"I don't want to take care of my child in this camp because I'm afraid he might even die in this camp", she said.
Muthana ditched her home in Alabama in 2014 to join ISIS in Syria, where she married several fighters and sent out tweets urging United States jihadis to "take down" President Obama and commit massacres at Memorial Day parades.
Hoda Muthana is now asking to come back to the US after spending a few years with the Islamic State terrorist group.
While it is unclear whether Begum committed any crimes and her legal status is uncertain, it's possible Begum could face charges for supporting IS if she returns to Britain.
She said she has appealed to the government to help get her back to the United Kingdom.
She was partly inspired by videos of fighters beheading hostages and partly by other propaganda films showing the "good life" ISIS could offer.
She gave birth to a baby boy last weekend, after she lost two previous children in Syria and named him after her first son.
She told the broadcaster: "I do feel that it's wrong that innocent people did get killed".
The attorney said it then, but it wasn't until Sunday - in her interview with The Guardian - that Muthana admitted herself that she was "brainwashed" and made a "big mistake".
Ms Begum - who is legally British - has asked for "forgiveness" and "sympathy" as she wants to return to the United Kingdom for the sake of her newborn child. It's one thing to kill a soldier that is fighting you, it's fine, it's self-defence.
But a different fan sounded a note of caution, remarking: "I think this is such a worrying topic to address on Instagram".
He wrote that the 19-year-old should "rot in hell" after marrying the "the world's worst terrorists" and that neither of them should be allowed to return to their home countries.
Isis bride Shamima Begum said Western air strikes against Syria were a "fair justification" for the Manchester Arena suicide bombing. Everything I've been through, you know. I know a lot of people, after they saw that me and my friends came, it actually encouraged them.
Three years ago, British teenager Shamima Begum ran away from her London home with two other school girls and joined ISIS.
Isis claimed responsibility for the bombing by Salman Abedi on May 22, 2017, which killed children as young as eight and wounded 139 people, saying it was in response to "transgression" against Muslims.
Her family's lawyer, Tasnime Akunjee, said he anticipated she would face criminal proceedings upon any return to the United Kingdom, but that it was the family's hope she would be given professional help following her experience in Syria.
You Can Never Go Wrong With Food
We do not know how it does it, but this food manages to hug us tightly as we eat all the stress away. Not the carbohydrates, but different categories for different days and different occasions.
In as much as most movies show how gambling is bad or addictive, look on the brighter side, it is a good way of making money. With so many people shaming gambling, directors are trying to put it out there that it is not as bad as people make it seem.
