ugh frustrated

Has anyone else's kids talked potty talk about poop and ever drew a guess a person with the infatuation of body parts? Just ridiculous because I think every kid goes through it and unfortunately I'm a terrible parent because my daughter went on about it on paper with neighbor kids and apparently I'm the reason she is exposed to this terrible behavior...seriously I've worked in an elementary school and I'm not the most terrible person..seriously I've worked with tons of kids and I'm doing pretty good in life but I'm still a terrible person and parent ...seriously this shouldn't be on facebook but I need some reassurance because I know I'm not doing anything wrong
