The book is short and thus moves quickly, making Boomer's transition from wariness to love seem a little implausible to adult readers, but the length and pace are most appropriate for the intended audience. The sentences, too, are short and to the point, making it a book perfect for reading out loud, either to an individual child or to a group of children. The watercolour illustrations also lead to the book's being read aloud, with colourful, vibrant illustrations filling the double page spreads. Although the realistic illustrations follow the action of the book, the moments of time chosen for illustration are original and unexpected. Because of the watercolour medium, the paintings are full of energy and motion and manage to capture emotion, as well.

This book would be an appropriate read by a librarian or teacher to a group of children to prompt or stimulate discussion about siblings and sibling rivalry. It would also be useful to parents looking to broach the subject with their child. Consequently, for readers looking for a book about the introduction of a new baby into the household, the positive, bright storyline and detailed, emotive illustrations make this book a good choice. For readers looking for a stand-alone story, Boomer's Big Surprise falls somewhat short as it lacks a storyline which would be attractive and interesting to all readers.

Recommended.
