What makes a family, really? Erin and Roderick are siblings who are always together and love making new discoveries. On a sunny afternoon, they have a picnic and playtime in the park with their friends and family but they start to notice differences. As the children and adults soak in the sunshine, Erin and Roderick begin to wonder what "Family" really means. In this beautiful story, children learn that families come in all shapes and sizes and that our differences are beautiful and amazing. With light-hearted storytelling and beautiful illustrations, this book opens the conversation about family units for children, adults, caregivers, teachers, and anyone who wishes to explore the wonderful world of blended families. It's the perfect gift for newly adoptive parents and families, and a great way for children to see diverse and multicultural families.
