A breastfeeding log built for the questions you ask at 3 am
What should I write down in a breastfeeding log?
Three fields are enough: the time the feed started, which side you fed from, and roughly how long it lasted. Which side was last is the field people reach for most, and the time the feed started is the one that produces every other useful number: feeds per day, and the gap between them.
What to log
Start time, side, and duration. Skip anything you would not want to type one-handed in the dark.
What it shows
Feeds in 24 hours, the gap between them, whether one side is being favoured, and cluster-feed evenings.
Best for
The early weeks, mixed feeding, returning to work, and lactation-consultant or child-health appointments.
Which side did I feed from last?
This is the question a breastfeeding log exists to answer, and it is the reason hair ties and safety pins have been used as trackers for generations. Recording the side at the moment you start means you never have to reconstruct it later, when you are least able to.
Alternating sides matters because supply responds to demand on each side independently. A log that shows one side used consistently more often is worth mentioning to a lactation consultant or child health nurse, especially if you notice a difference in fullness.
How long should a breastfeed take?
There is no single right answer, and this is the most common reason parents worry unnecessarily. Newborns commonly feed for 20 to 45 minutes; older, more efficient babies may finish in 5 to 10 minutes and be perfectly well fed.
Because duration varies so much between babies, the useful signal is your own baby’s pattern over a week, not a comparison against a number from a forum. A feed that suddenly takes much longer or much shorter than that baby’s normal is the thing worth noticing.
How do I know my baby is getting enough milk?
Milk volume cannot be measured at the breast, so the published signs are indirect: wet nappies, dirty nappies, weight gain, and a baby who is generally settled after feeds. From day five onwards, five or more heavy wet nappies in 24 hours is the commonly cited marker.
This is why a breastfeeding log is far more useful when nappies sit next to it. Feeds alone cannot tell you about intake; feeds plus nappy output can, and that pairing is exactly what a clinician will ask you to describe.
- Five or more heavy wet nappies a day from about day five
- Pale, close to odourless wee
- Steady weight gain along the baby’s own curve
- Dark, strong-smelling wee or fewer wet nappies: contact a clinician the same day
What about pumping and mixed feeding?
Once expressed milk or formula enters the picture, a log stops being optional for most families, because the total is now split across sources and nobody can hold it in their head. Log pumped sessions as their own entries with volume, and bottles with what was actually taken.
BubSync records breastfeeds, expressed bottles and formula in the same feeding timeline, so the daily picture stays whole rather than living half in an app and half on the fridge.
How do I log pumping without ruining my feeding totals?
Pumping is output and a bottle is intake, and most trackers make you record the first as the second. Log a 120 ml pump as a bottle feed and the day now claims a baby drank 120 ml they never saw, which is the number a child health nurse will ask you about.
Breast pump is one of BubSync’s eight built-in types rather than a workaround. A session records which side or sides you pumped, the amount expressed in ml or fl oz, and optionally a duration on the stopwatch. Expressed totals are summed under their own type, so supply over a week and intake over a week are two different lines rather than one confused one.
That separation matters most in the weeks around going back to work, which is also when the most people are helping. A partner giving the 10 am bottle logs intake; you log the session at your desk. The two add up to a picture of supply against demand that neither of you could keep on your own.
- Left, right, or both, so alternation stays honest at 5 am
- Amount expressed in your own units, kept out of the bottle-intake total
- The stopwatch is optional: a session with only an amount is a complete record
- Free on every plan, and it saves offline like everything else
What to record, and what it answers
| Field | Why it earns its place |
|---|---|
| Start time | Produces feeds per 24 h and the gap between feeds: every other number derives from it |
| Side | The single most-reached-for field; keeps alternation honest when you are half asleep |
| Duration | Meaningful against your own baby’s pattern, not against another baby’s |
| Wet nappies | The practical proxy for intake that cannot be measured at the breast |

Frequently asked questions
- What should I record in a breastfeeding log?
- The time the feed started, which side you fed from, and roughly how long it lasted. Side is the field parents reach for most often, and start time is what produces feeds per day and the gap between feeds.
- How many breastfeeds a day is normal for a newborn?
- Roughly 8 to 12 feeds in 24 hours is the commonly published range for the early weeks, including overnight feeds. Feeds are usually irregular rather than evenly spaced, and cluster-feed evenings are common.
- Is a breastfeeding app better than a notebook?
- Only if it is faster to use one-handed in the dark. The advantage of an app is that it derives the gap between feeds automatically, keeps the record when your phone dies, and can be seen by a partner. A notebook does none of those, but a notebook you actually use beats an app you do not.
- Can I track breastfeeding without internet?
- Yes. BubSync saves each feed on the device first and syncs it when a connection returns, so logging in a nursery with no signal works normally.
- Can a lactation consultant see my log?
- You can show or share the timeline at an appointment. BubSync keeps feeds, nappies and sleep in one view, which is the combination lactation consultants and child health nurses usually ask about.
