Be open to seeking help. I know of a few parents who have put together a network of sensitive specialists who could answer questions on specific questions. Therefore the child gets authentic answers for his questions. These could teachers, psychologists, doctors, lawyers and even friendly police officers.
Information is the armour to protect the child from fears that might arise in their heads. It is also the most potent weapon against things that can assault the child’s mind. Nurture the child’s mind. Make it curious. Make it fearless.
A fearless mind. The best gift you can ever give a child.
