It doesn't matter whether you have kids - you will enjoy this book. Karen Alpert is the author of a popular blog, Baby Sideburns, and she brings the same conversational humor to her book. That being said, if you don't like harsh language, you might not find it as funny as I did (but if you don't like harsh language, you could probably have figured that out from the title).
It's a very short read but that fit it really well. A number of times I interrupted my husband to read parts to him, and I was forbidden from reading it in bed because my giggling kept him awake. (Sorry, love!)
Right in the middle of the book is one chapter dedicated to a serious topic: postpartum depression. Alpert doesn't go too in-depth, but she tells a short and very personal story about her own realization of just how drastically your life can change once you have a child. It was only three pages, but that was the part that stuck with me the most.
Overall: 5 stars. It's fun, it's quick, and it still manages to give you good advice.
