we were listening to radio (with 4 and 6yo) and host mentioned something about prostitutes (regarding TV show) so my kid ask me what is prostitute? someone who does sex for money obvious question followed, what is the sex? it's exercise done by adults in bed when they wanna have baby or sometimes even when they don't want because they just like the exercise kids lost interest after that, now tell me, did I lie? by all accounts sex is pretty good calorie burning exercise btw. I told them already like year before that how is baby done, that penis goes inside vagina, then sperms go from penis to egg inside and there will grow baby, didn't even bother with some bees and other crap, but dunno how much kids remembered because they were not interested about it. we also watched already around that time amazing (dubbed) TV show Il était une fois... la vie (Once Upon a Time... Life) though I think it's more suitable for old children, I liked it when I was in primary school we still though tell christmas gifts are brought by santa claus/baby jesus
