Nappy tracking guide
Why Nappy Counts Matter Most in the Newborn Weeks
You cannot measure what a breastfed baby takes in. In the newborn weeks, that makes nappies one of the few signals available about whether feeding is going well. And how many you changed today is not something anybody remembers by evening, so it has to be captured as it happens.

Why count nappies at all
The question new parents ask most is whether the baby is getting enough. Breastfeeding gives you no volume, and daily weighing is too noisy to answer it.
That leaves nappies. You cannot measure what goes in, so you count what comes out. It is an imperfect signal, but it is available every single day.
Wet and dirty carry different information
Collapse them into one field and neither is readable afterwards.
| Type | What you track | What to record | | --- | --- | --- | | Wet | Count | A tick per change | | Dirty | Count plus character | Colour, consistency, amount |
Counting is enough for wet nappies. Dirty ones need the extra detail or the record loses its value later.
Recording colour without agonising over it
Colour is the field memory handles worst. "Was that yellow or green?" blurs within hours.
Defining a few options in advance and picking from them is easier than describing it fresh each time. Yellow, green, brown — a short list keeps the decision from becoming a chore.
That said, anything close to white, anything with red streaks, and anything black are not entries to log and move past. Those warrant contacting a clinician.
Reading nappies next to feeds
Nappy records are far more useful beside feeding records than alone. Do the days with more feeds line up with more nappies? When feeding dipped, did output dip too?
If you are breastfeeding, pairing this with breastfeeding logs is particularly worthwhile — it puts the side you cannot measure next to the side you can observe.
When to skip the log and call
Records help you know what is usual. They are not a reason to wait. Contact a clinician rather than tidying up your log if you see:
- Wet nappies clearly reducing compared with your baby's normal
- Blood in the stool, or stool that looks close to white
- Diarrhoea that continues, or a baby who becomes floppy or unresponsive
The log's role is to describe the situation accurately once you are talking to someone. It is not a tool for deciding how serious something is.
Frequently asked questions
- Do wet and dirty nappies need separate fields?
- Yes, because they tell you different things. Wet nappy counts relate to fluid intake, while dirty nappies need colour and consistency recorded alongside the count.
- How many a day is normal?
- It varies considerably with age and feeding method. Rather than memorising a number, learn your own baby's usual pattern so you notice when today departs from it.
- The colour looks different today. Should I photograph it?
- A photo helps, since colour is hard to describe and memory is unreliable. But clearly abnormal colours — white, red, or black — call for a clinician rather than a log entry.
- No dirty nappy for a few days. Can the log tell me if that is fine?
- It tells you exactly when the last one was, which is useful. What counts as normal varies with age and feeding method, so if your baby seems uncomfortable or you are worried, check with a clinician.
- Can nursery or a sitter's changes go in the same log?
- Pooling them gives you the true daily total. Marking who did the change makes it easier to reconstruct the daytime picture afterwards.
