The Chron has launched a blog to help young parents cope with the stress of raising kids while “desperately hanging on to their coolness,” according to a story introducing the blog. The blog’s name is “The Poop.” It is the brainchild of Chronicle writers Heather Maddan, Aidin Vaziri, Delfin Vigil and Peter Hartlaub, all of whom are relatively new parents. The Poop will include commentary, reviews, shopping suggestions and weekend activity ideas.
