Officials have been forced to take action in more than 150 cases where children were in danger of being radicalised, figures show.
The family courts – which have powers to take youngsters into care – have seen a wave of cases driven by returning jihadi mothers, a report revealed.
The ground-breaking study by the Henry Jackson Society (HJS), an influential security think-tank, concluded Islamic State bride Shamima Begum is likely to see her Syria-born son Jerah removed from her care if she manages to return to Britain.
She would also be forced to undertake an intense de-radicalisation programme in an attempt to change her extremist behaviour.

And the 19-year-old can be expected to be placed under surveillance by the authorities with strict conditions on what she does and who she meets, it said.
Begum’s likely fate was gleaned from the HJS’s study of the known English court cases involving children in need of protection from radicalisation during the Islamic State era.
The report found that between January 2013 and this month, 156 children were in the family court over extremism.
An analysis of 20 cases, involving 43 children, found 52 per cent of families had at least one member who had joined IS.
In 55 per cent of cases, the family was influenced by Al Muhajiroun, the banned terror group formerly led by hate preacher Anjem Choudary.
One in five radicalisation cases involved children who were home schooled, suggesting that keeping children isolated from mainstream education made it easier to indoctrinate them.

The study also found that girls like Begum who joined IS were more likely than boys to have self-radicalised by independently seeking out extremist material.
The report, Radicalising Our Children, by HJS terrorism specialist Nikita Malik, warned the courts were ‘frequently powerless’ to take steps to protect the welfare of children at risk of brainwashing.
It concluded guidance to judges on radicalisation should be updated so they could make decisions on the ‘real possibility’
