My first daughter worked it out for herself when she was about 10. My second daughter is now 8 and does not know. Not sure what will happen if she ever Googles her Dads name.

Something I will need to think about soon I fear.
However my first daughter handled it well and used to bring her college friends to models parties we held in London. Big parties that we held in top night clubs like Stringfellows, before it went into lap dancing. She even told her friends not to take any notice of the guys asking her if she wanted to be a model.
