Caution...Potty Talk

I am starting to see a theme with several of my posts. First off, I come from a family that has no problem with dinner conversation revolving around potty topics. In fact it pretty much is brought up at every family dinner. Well, last week my brother (it is just him and I as far as siblings) and his girlfriend, Melissa, came down to visit us and hang out. Lately, Camille has discovered her voice. She is much more vocal when doing anything. Well, as we were driving Camille felt like loudly grunting and growling for about 20 minutes as she was trying to poop (I guess it is more work since she has started eating solids). I'm serious it was 20 minutes. At first we were not sure if she was just having fun making the sound but soon the smell told us that something had accompanied the noise. We all got a little chuckle out of it. Later in the day we were back in the car and Melissa randomly says, "That whole sound thing that Camille made is still cracking me up. I wonder why?" So Jordan chimes in, "Because we all wish we could make that same noise around people when we have to go pooh." And we laughed about it for quite awhile.

So like, at what age do people learn that it is not appropriate to make that grunting noise?????*****totally random kid picture*******
