What this book is about
- How Big is Our Baby? A 9 Month Guide for Soon-to-be Siblings explains pregnancy from the perspective of a child waiting for their new sibling to arrive.
- The book compares the developing baby’s size to objects children can picture easily—starting as small as a speck of sand, then a jelly bean, a mango, and eventually a watermelon.
- It gently introduces the stages of pregnancy, showing how the baby gradually grows eyes, ears, and other features.
- The story acknowledges the emotions that come with becoming a big brother or sister, helping children feel included in the journey.
- It assumes a heterosexual couple as the baby’s parents, which may not reflect all families, but parents can adapt the story to fit their own situation.
- At the end, the focus is on welcoming the baby sibling with love and excitement.
