One of the great things about having kids is teaching them things. It is amazing when you tell them to say "mama" and they do. It is amazing to teach them colors, shapes, animals names, and noises. It is charming to hear their own little vernacular and mispronunciations. Then comes the point when you need to watch what you say around them. When you catch your youngest daughter saying "C'mon Dude!" because you say it when you are frustrated by traffic. And when you catch your older daughter saying "Dangit!" and the younger one mimicking her of course.
