There is no one size fits all when it comes to families. They can be large or small, blended or shared, here or there. The families in this book might have one dad or two moms. They might have grandparents or not. No brothers or sisters, or a lot! Your family or my family, whatever it's like, it's the perfect fit. The only tradition that matters in these families is that they love each other. Board book. By Kathryn Cole, illustrated by Cornelia Li. Suggested ages 0-4.
