Be cautious about conversations with children that involve sex. It is understood that children ask honest questions about sexuality and teenagers might seek advise. Listening with respect for the child is appropriate. Joking around with children in ways that encourage promiscuity or the acceptance of sexually explicit material is dangerous for you and the children. In all things, respect the integrity of the child.
Abused children are sometimes fearful or distrustful of any physical contact.
Most of us sense the difference between positive caring intentions and those which are meant to exploit us. Use your common sense and good judgement to guide you in protecting the personal space of the children in your care.
