There's Going to be a Baby by John Burningham & Helen Oxenbury
When is the new baby coming? What will we call it? What will he do? We don’t really need a baby, do we? With sensitivity and wit, John Burningham follows the swirl of questions in the mind of a young child anticipating a baby sibling with excitement, curiosity, and just a bit of trepidation. In perfect tandem, Helen Oxenbury captures the child’s loving interactions with his mother — along with the fanciful future scenarios he imagines for the new family member he has yet to meet. Combining a warm, timeless story with illustrations both freshly enchanting and wonderfully nostalgic, this gorgeous book has all the hallmarks of a classic.
