'She said she'd had two other babies who had both died.'
'Speaking from a camp in Syria, she said she was nine months pregnant and wanted to come home for the sake of her baby.'
So it took her until pregnancy #3 to realise a war-torn Syrian battlefield isn't the best place to raise a baby...
If she were to return to the UK, I highly doubt she'd be able to get any sort of employment without a new identity, so her and her baby would be living on the tax payer.
If it were just her, I'd say leave her in Syria. She's made her bed and she should lay in it now. However, assuming the baby survives, it shouldn't have to suffer for their idiotic mother's choices.
