  • This is the second children’s book of his that I’ve read and loved…brilliantly written and wonderfully illustrated. It was already abundantly clear that Daniel Collins has a unique talent for making complicated feelings easily understandable for young readers but to be able to address anger and frustration in such an entertaining, humorous, and ultimately moving way is a true testament, not only to his abilities as a children’s author, but to his character as a person…this book is truly moving in a way that can’t be faked. Whether you’re a parent and/or grandparent of children of any age or simply an adult recalling how difficult some days were growing up and/or can still be, this book and this entire concept is a true masterpiece in the way it simplifies and teaches self-awareness and empathy. Well done. 👍

  • Finally! a great kids book that teaches kids, self awareness, problem solving, accountability, and determination. The illustrations are on point! This book just took me back to my own childhood when I was young dealing with everyday kid problems just trying to figure this new world out!

  • I came to this book for the art and stayed for the message. It’s important as a parent to be open and talk about when you aren’t having your best day. I strive to be vulnerable and share with my kids when I’m struggling so they know it’s okay to not be okay.

  • What I love is how Rain Makes a Farm subtly weaves together valuable lessons about caring for animals, understanding where our food comes from, and the importance of hard work and cooperation on a farm all told through the eyes of a dog!

  • This is a beautifully conceived piece of children’s literature with numerous life lessons (love of animals, agricultural science, conservation, sustainability, etc) included in its spoonful of sugar. The author’s use of “rare words” in easy to grasp contexts also makes learning new words simple for new readers and the illustrations are wonderful. This is definitely a children’s author to keep an eye on and his work makes a great addition to any children’s library collection.

  • As a parent to an 18-month-old, I’m always looking for ways to entertain him that also support his development, and that we can both enjoy. This book definitely checks those boxes! It delivers thoughtful messages through a wonderful story, and while he doesn’t fully understand the words yet, my son absolutely loves the illustrations. This one will be in regular rotation during our reading time. I’m looking forward to more from this author!

  • I love how many teaching points are made so easily in this book. From learning that dandelions are edible, to each animal having a specific job on a homestead.. The connection between Rain and her farm is incredibly heart warming! She clearly loves and engages with all of the creatures she is in charge of, right down to her plants. If you are looking for a wholesome book that you may also enjoy learning from, this is the one!
