Nappy notes: what to record (and what not to) in your baby log

A new-parent guide to logging nappies, feeds, sleep, symptoms, medicines and notes without over-recording every detail.

AcornioUpdated 27 May 2026

New parents are often told to “keep an eye on feeds and nappies”, but that can quickly become a lot.

What counts as useful? Do you need every minute, every ounce, every nap, every cry? What if you miss something?

A good baby log should help you remember the basics and prepare for conversations with a midwife, health visitor, GP, doctor or paediatrician. It should not become a second baby to look after.

The essentials

What to logUseful detailWhat you can skip
FeedsBreast/bottle/expressed milk/formula/solids, rough time, rough amount if knownPerfect timings if they make you anxious
Wet nappies/diapersWet, dry, lighter than usual, fewer than usualWeighing nappies unless advised
Dirty nappiesColour, consistency, frequency, discomfortLong descriptions every time
SymptomsFever, vomiting, rash, tummy pain, unusual sleepiness, poor feedingRepeatedly checking for symptoms when baby seems well
MedicinesName, dose, time, reasonGuessing doses from memory later
NotesIllness, travel, vaccines, poor sleep, nursery/daycare updatesEvery small mood change

Feeds

For feeds, record the shape of the moment:

  • breastfeed, bottle, expressed milk, formula or solids
  • rough time
  • rough quantity in ounces or millilitres if known
  • whether baby fed normally, less than usual, or seemed unsettled

Examples:

8am breastfeed, usual length, settled after.

2pm bottle, 3 oz / 90 ml, left some.

Nappies and diapers

For nappies, it helps to record:

  • wet, dirty, wet and dirty, or dry
  • colour if it is notable
  • consistency: watery, loose, soft, hard, sticky
  • whether there was straining, discomfort, leak or blowout

You do not need to name every shade. “Yellow”, “greenish”, “brown”, “pale-looking” or “red streak” is enough to help you decide whether to ask for advice.

For colour guidance, see the baby poo colour chart.

Symptoms

Log symptoms when they happen, not because you are trying to find something wrong.

Useful symptom notes include:

  • what you saw
  • when it happened
  • how long it lasted
  • whether baby was feeding and having wet nappies
  • what happened next

If your baby seems very unwell, has breathing difficulty, signs of dehydration, a non-blanching rash, a high fever, blood in stool or vomit, or symptoms that feel sudden or serious, seek urgent medical help.

Medicines

Record medicine doses clearly:

  • medicine name
  • dose
  • time
  • reason
  • whether it was prescribed or advised

Use regional names carefully. In the UK, parents may say Calpol. In the US, parents may say acetaminophen or Tylenol. The active ingredient and dose matter more than the nickname.

What not to record

You probably do not need:

  • every tiny fuss
  • exact timings when a rough note is enough
  • full nutrition analysis
  • repeated reassurance checks
  • charts you never use
  • notes that make you feel worse rather than clearer

The question is: would this help if you had to explain the last few days to someone?

If not, skip it.

How Acornio helps

Acornio is designed to keep baby logs practical by bringing food or feed notes, stool or nappy observations, symptoms, medicines and notes into one calm timeline.

It does not diagnose or tell you what a nappy means. It helps you record enough useful detail so you are not trying to reconstruct everything later.
