In this way, peplums also help those with less shapely body types by creating new Coke-bottle curves. Personally, I’m grateful that they mitigate signs of a "food baby," more commonly known as bloat.

I used to (and occasionally still do) marvel at the sheer variety and obscurity of associations, from the General Society of Mayflower Descendants to the National Grange of the Order of Patrons of Husbandry to the Puppeteers of America. Now I've come to believe that for almost any topic you can think of there's at the very least a web page and also likely a blog dedicated to that subject. Food babies are no exception, with The Food Baby blog ("Celebrating the Pursuit of Gluttonous Endeavors") a going concern since January, 2011.
