Everyone has been around a little 10lb baby that can rip a healthy loud toot. But let's keep it real here, it can be at the most in opportune time when there are a ton of people around and it's quiet leaving nothing but the rippling wind out of her diaper padded toosh to ring through the...waiting room perhaps. What's so funny is that they are so aggressive, they can almost be mistaken for my own gas. It's horrifying...I try to make it obvious it is my sweetest little 5 month old, but let's be real, some people are scoffing at me like I'm the culprit. I say things really loud like "Ohh look at that face, are you pooping!" Then giggle insecurely and smell her diaper. 
This is the face of danger...when this starts, I run out of quiet areas into the open to avoid all mishaps.
