When author Julia Fierro started the Parenting Confessional Tumblr last month, she got more than she bargained for. Fierro had been hoping that it'd just be a fun way to promote her new book, Cutting Teeth. But in only a few weeks, the Parenting Confessional Tumblr amassed more than 10,000 followers and was deluged with submissions from parents wanting to share their stories, ranging from hilarious to horrifying.

Below we've grabbed some of the most shocking confessionals. You can see others (or submit your own, you terrible parent you) here. Cutting Teeth, is out today.
