How to Catch a Babysaurus, written by Alice Walstead, is the newest book in the How to Catch... series. We have read several of them and always enjoyed them. In this story, the boy's family has a new baby, to him, it is a babysaurus. His BFF tells him about his experiences with a babysaurus, so he gets his traps ready to catch it. It smells, makes noise, touches stuff and eats, so he used those things to make his traps work. But he realizes that there are things he likes about the baby.

We enjoyed this story and ended up talking about how babies are like dinosaurs. My middle grandchild told the younger one that he was stinky, and cried loud when he was little. She also said he took all mommy's time to feed him. We laughed about that. I always get the kids to talk about the traps that are set and how they worked or didn't work. The illustrations in this series are always excellent and this book is no exception. A fun read for little ones.

How to Catch a Babysaurus, written by Alice Walstead, is the newest book in the How to Catch... series. In this sweet and hilarious book, a young boy knows that someone's on the way to live at their house with him, but he doesn't exactly know what to expect. His best friend has had a similar experience, and tells him that a Babysaurus is coming. Through a fantastic story and illustrations, our protagonist comes up with ways to shield himself and his things, but of course we have to have a happy ending!

I loved this book, and the sweet story line. I can definitely picture this being a great book to share with young readers, especially those interested in STEM or those who are a little hesitant about a little sibling. Thank you to NetGalley and to the author and publisher of this book for an ARC in exchange for an honest review.

We are huge "How to catch a…" book fans in this home!! I know there are a lot, and we own several of them. I have said this in another book review of the same series. My kid was so excited to read these!

How to Catch a Babysaurus is as cute and fun as it sounds. This book is about having a new little one coming. This book is perfect for families that have a new addition. I wish we would have had this two years ago! Even if you don't have a little new one, it's good for any type of change. I will be adding this one to our library. The illustrations are amazing and one of my favorite things about this series. I can't wait to see what they do next.

Many thanks to Sourcebooks Wonderland and Netgalley for an e-ARC. All thoughts an opinions are my own.

The newest installment in the How to Catch series is as cute, clever, and fun as its predecessors. This time, we follow a family preparing for a new arrival. The only child is understandably confused about what this change means. Through a series of adorable, action-packed illustrations, we get to watch the journey of adjusting to life with a new sibling and the blossoming bond between them.

The illustrations are vibrant, dynamic, and engaging; perfect for capturing young readers’ attention. As always, the rhymes are quirky and fun, right in line with what fans of the series have come to love.

I’d absolutely recommend this book to children ages 3–10, especially to families navigating the uncertainty and excitement of welcoming a new sibling.

Thank you to NetGalley and SOURCEBOOKS Kids for the eARC in exchange for an honest review.

First - thanks to Netgalley and Sourcebooks Kids for sending along an ARC of the latest book in the “How To Catch A…” series.

This book would be the perfect present for any child about to welcome a new baby into their home (meaning my 4.5 year old couldn’t relate, as she is and always will be an only child). She still really enjoyed this, and thought the pictures were cute and the rhyming scheme was easy to follow and flowed well.

As soon as we finished reading, she ran to the bookshelf in her bedroom and pulled out one of the physical copies from this series that we have, and wanted to read that one as well. She was so excited that the children in the illustrations were the same within each book - continuity is important!

Our family already owns How to Catch a Daddysaurus and How to Catch a Mamasaurus along with a few other titles from Alica Walstead. How to Catch a Babysaurus is a cute addition to the series, particularly for families expecting a new sibling. The playful comparison between a human baby and a babysaurus adds a fun and imaginative twist that will captivate young readers. The book’s emphasis on action words enhances the excitement, and the illustrations are as engaging as ever, beautifully bringing the story to life.
Thank you to NetGalley and the publisher for providing me with an advance reader copy in exchange for an honest review.

Thank you to NetGalley and Sourcebook Kids for an advanced read copy of one of the latest "How to Catch a..." book!
How to Catch a Babysaurus by Alice Walstead is yet another adorable rhyming book to add to this series.  This book would make a cute gift for siblings in a family expecting a baby as it tells the story of a young boy expecting a new family member except the baby is a dinosaur!  The illustrations are engaging and my seven year old just loves this fun series! 

[Shan · Rating 5 out of 5]

Such a fun and cute book! I love how the author decided to take a familiar topic (for a lot of kids) and add a special spin on it. Combining a relatable event with *dinosaurs* is so clever, and worked really well! Additionally, it was amazing how much personality the author gave to the Babysaurus, even though readers barely see and never "hear from" the character. Lastly, I definitely give lots of credit to the illustrator for the beautiful coloring and vivid detail on each page. Bravo!!

Thank you to Sourcebooks Kids for the advance copy!

This is a cute children's book that is perfect for families that are welcoming new babies. It includes all sorts of experiences that the new older siblings will experience, and introduces them in a fun and engaging way. The illustrations are so adorable, and the text was easy to understand for young children.

[Liz Benbow · Rating 5 out of 5]

What a great new addition to the How to Catch book series! My students will love this one. It would also be an excellent gift for a child that’s expecting a new baby sibling in their home. The introduction of the baby as a “babysaurus” will help kids relate a new family member to something most kids already love (dinosaurs!).

Thank you to NetGalley for this ARC in exchange for my honest review.

I received an electronic ARC from SOURCEBOOKS Kids through NetGalley.
Readers may identify with the concerns raised about a babysaurus entering their lives. We see how he sets traps that fail and finally comes to appreciate how important the babysaurus is. The illustrations capture the humor and fun along with the real concerns older siblings may feel.

[Sky · Rating 4 out of 5]

This is definitely a cute silly book with great illustrations. The colors are very vibrant and the artwork is engaging enough to tell its own story alongside the word. I can imagine this being a crowd favorite for many families. my toddler for sure loved pretending to help catch the dinosaur.

This was another netgalley arc I got to read with my daughter. She loved this one.

[Jessie (Saffity) · Rating 4 out of 5]

A cute book that shows the chaos a new baby in the house can cause. My kids (5 and 2) found this book quite entertaining, especially all of the traps set up to catch the babysaurus. The illustrations were very cute, and rhyming style was fun. Just a fun book about what having a sibling can be like with little funny bits along the way. We read this book through NetGalley.

The latest rhyming picture book in the popular How to Catch series. This time the hunt is on for "a Little One, who does not walk or speak." A silly book for older siblings about the new baby that's coming.

"He told me about this weapon,
one that's sure to blow your mind.
'It's a Secret Super Smelly Bomb --
never catch a Babysaurus from behind.!'"

What a great book for any older brother or sister with a new baby or baby on the way! Loved the rhyming and vocabulary provided in this book. The illustrations are perfect- so colorful and greatly depict the story. Thank you for allowing me an ARC on this cute story!!

[Bookish Venturess · Rating 5 out of 5]

This was such a cute story. My daughter and I loved this one so much. It was such a cute book about a sibling. My daughter was laughing at some parts. She really liked how the baby was compared to a dinosaur and that she agreed with several of the comparisons.

[Jenni · Rating 5 out of 5]

Super cute and colorful illustrations. this one, like the others in the series, tells a cute story. Will the babysaurus be scary? Smelly? Loud? A fun book to read with someone who is about to become a big brother or sister.

[Jenn Georges]

Super cute story. This will make the kiddos laugh. This is a beloved series in my library and can’t wait to get a copy in the library for them! We are slowly building our collection. Prefect for K-2 students. Its a fast and easy read aloud.

This boy character is sure to get ready for a new baby by plotting to catch and keep his things safe from a new Babysaurus. It has a loud cry, and a smell, and builds traps to catch this creature. Learns to like the smiles and laughs and funny things it does. Some imagination this boy has.
