However generic question doesn’t resolve anything for a child specifically. What matters is you knowing the reasons your child is worried. Getting them to share and support them through the issue they may be facing.
So my recommendation would be to start from the space that the child may be worried and you would want to speak to the child, to know.
Its better to err on this side that start from a belief that the child (given the age) may not be worried and we don’t even try to know..
