My oldest knows...he's sneaky and sorta found out on his own and when he asked me about it, I told him that I handle some marketing for some adult entertainment companies, and I stressed the ADULT part. My next child is only 14 months younger in years, but waaaayyyy more immature, so he doesn't know, and my girls are just 3 and 15 months, so they have no clue, of course.
I will tell them, when they are older and more mature, but on a need to know basis....
