Thank you for everything: how to tell your parents they are going to be grandparents

From the cover to the second-to-last page this is a thank-you to your own parents. It is about the nights they stayed up, the food that was always ready, the times they came to collect somebody without asking why. Small memories rather than big words.

The title and the cover give nothing away. No baby, no bump, no baby clothes. Whoever unwraps it genuinely believes it stops at the thank-you, which is exactly the point.

The last page turns it around: you are going to be grandparents, and we are going to be parents. That is the first time it is mentioned at all. You write that line yourself, word for word.
