how often do you have a wash?

My wife and I both take showers everyday, no matter what time of year that it is. I would say something to her if she did smell and I knew she wasn't taking a shower in days. I can understand missing one day here and there, but no a constant thing. Also, we give both of our children baths every night before they go to bed as well. We are trying to teach them that they should take one every night, no mattter what.
