Admittedly because I don't have children nor do I work with them for any job, I didn't realize how uh..smelly they could be.

I remember we had to use our nephews' bedroom to sleep when visiting a sister and her family. Boys were 9 and 7 and slept somewhere else in house, on behalf for the guests. I was trying to sleep, thinking how sweaty and smelly the bedroom was.

And probably the parents became immune to it that they didn't notice much themselves to do anything in advance about it.
