A symptom diary framework — what to record, how to record it, and how to summarise weeks of observation onto a single page a GP can actually read in the ten minutes you have.
The opening statement, the three questions worth asking, and the exact words to use if you are dismissed again — including how to request that your concern be documented in your baby's notes, and how to ask for a second opinion.
An honest chapter on what treatments actually do — alginates, PPIs, dairy elimination, hypoallergenic formula — with realistic timelines and a clear picture of what improvement actually looks like. Because it is rarely linear, and knowing that changes how you read what is happening.
