Enter today's feeds, wet diapers, latch, and pump output to get a Supply Score that answers the question every breastfeeding parent is asking.
The most stressful question in early breastfeeding is whether your baby is getting enough. You cannot measure what is transferred during a nursing session the way you can with a bottle, so most parents are left guessing. This tracker replaces the guesswork with a Supply Score built from the real indicators that matter: how many times the baby fed today, average session duration, latch quality, pain level, wet diaper count, pump output if you are pumping, and baby weight compared to birth weight. Enter your current numbers and the tracker gives you a score, a week-by-week weight chart, and a plain-English advisory.
The tool is not a substitute for a lactation consultant or pediatrician. If something concerns you, see someone. But for the space between appointments — the 11 PM moment when you are not sure if five wet diapers is fine or worrying — having a structured check-in with actual output helps more than an online search spiral.
The three supply indicators that actually predict whether baby is getting enough
The tool surfaces three primary indicators and weights them heavily in the Supply Score: wet diapers per day, weekly weight gain, and latch quality. Six or more wet diapers in 24 hours is the most reliable single signal that intake is adequate. Weekly weight gain in the target range of 5 to 7 ounces for a full-term baby from weeks two through four is the next most important signal. Latch quality on a 1-to-10 scale affects how efficiently milk transfers and how sustainable feeding is for you.
Pump output is not weighted as a primary supply indicator, and the tool makes this explicit. Babies transfer milk two to three times more efficiently than even hospital-grade breast pumps. Low pump numbers do not mean low supply. If wet diapers and weight gain are on track, the supply is there regardless of what the pump shows. This distinction alone prevents a significant amount of unnecessary supplementation.
Pain during feeding is tracked because persistent pain above a moderate level almost always indicates a latch or positioning issue that, if unaddressed, tends to reduce feeding frequency and can affect supply over time. The tracker flags pain levels of 7 or above with a recommendation to see a lactation consultant, not as a warning label, but as a specific, actionable step.
Feed count and session duration: finding your baby's rhythm
The tracker fields ask for Feeds Today and Average Session Duration in minutes alongside Baby Age in weeks. These three inputs together give context the others cannot. A two-week-old who nurses eight times for 20 minutes and produces seven wet diapers is in a very different feeding situation than a ten-week-old with the same numbers. Baby age calibrates the targets.
Target feed counts shift as the baby grows. Newborns typically need 8 to 12 feeds per 24 hours; by weeks 10 to 12 many babies are settling into 7 to 9. The tracker adjusts what counts as adequate based on the Baby Age you enter, so the output stays relevant as your feeding relationship changes.
For exclusively pumping parents, session duration and pump output per session tell a more complete story than a single daily total. The pumping log tab in the tool lets you track per-session numbers and trends separately from the main feeding dashboard.
Reading the baby weight chart and what gain rate means
The Baby Weight Curve chart plots current weight against birth weight over time. You enter birth weight and current weight, and the tracker calculates weekly gain rate and shows whether it falls in the typical range. Most full-term babies lose 7 to 10 percent of birth weight in the first few days and regain it by 10 to 14 days old. After that, gains of 5 to 7 ounces per week are the usual target through the first three to four months.
The chart is not a pediatric growth chart and does not replace well-child visits. It is a quick visualization to help you see whether the trajectory is moving in the right direction between appointments. If weight gain looks low on the chart, that is a conversation for your pediatrician, not a reason to stop feeding or start supplementing without guidance.
Enter weights from your pediatric appointments rather than home scale measurements when possible. Scale-to-scale variation is real, and consistent weights from the same scale at the same clinic are the most comparable numbers.
The pumping log and what exclusively pumping parents need to track differently
The Pump Output Today field in the main dashboard asks for total ounces in the day. For exclusively pumping parents, the pumping log view adds per-session tracking, output trend over time, and guidance specific to maintaining supply through pumping rather than direct nursing.
Exclusively pumping requires 8 or more sessions per 24 hours in the early weeks to establish supply. The tracker notes this target and flags when daily session count falls below it. Power pumping — a pattern of 20 minutes on, 10 off, 10 on, 10 off, 10 on — is mentioned in the how-to section as a technique some providers recommend for supply building, without prescribing it as a requirement.
Pump part replacement matters more than most parents realize. Valves and membranes typically need replacing every two to three months. Worn parts significantly reduce suction efficiency. If your output has gradually declined without a clear reason, part age is often the culprit and worth checking before troubleshooting anything else.
What to bring to a lactation consultant appointment
This tracker produces a printable feeding data summary designed specifically for lactation consultant appointments. Instead of narrating five days of feeding from memory, you can hand over a snapshot showing feeds per day, average duration, latch score, pain level, wet diaper count, pump output if applicable, and the Supply Score trend.
A good LC appointment moves faster when the baseline is already established. The practitioner can focus on observation, hands-on support, and problem-solving rather than spending the first twenty minutes gathering history. Log it consistently and you will have something real to show your provider.
How to use it
- Enter Baby Age in weeks and today's Feeds count, then set Average Session Duration to how long nursing sessions typically run today.
- Rate Latch Quality from 1 to 10 and Pain During Feeding from 0 to 10 — both honest assessments matter for the Supply Score.
- Fill in Wet Diapers Today and enter current Baby Weight and Birth Weight in pounds.
- Set Pump Output Today if you are pumping, and select your Feeding Method from Breast Only through Combo.
- Read the Supply Score and the plain-English snapshot, then check the Feeding Snapshot panel to see which indicators are meeting targets.
- Switch to the Baby Weight Curve chart to see weekly gain rate against the target range, and use the print report to share the summary with your pediatrician or LC.
Who it's for
- New parent anxious about low wet diaper count — A parent whose newborn had four wet diapers at day 8 enters the numbers, sees the Supply Score flag, and brings the tracker printout to the same-day lactation appointment instead of waiting for the scheduled visit.
- Exclusively pumping parent tracking supply trends — An EP parent tracks daily pump totals across six weeks and spots a gradual decline starting at week 5 that correlates with dropping below 7 sessions per day during a return-to-work transition.
- Person managing high pain scores at latch — A parent tracking latch scores of 4/10 and pain of 7/10 for three consecutive days uses the tracker's printout to communicate the pattern clearly at an LC appointment, getting a diagnosis of shallow latch rather than spending the session rebuilding history.
- Parent tracking combination feeding — Someone combo-feeding uses the tracker to monitor whether breastfeeds are holding steady as formula supplementation increases, watching wet diapers and weight gain to calibrate the balance with their pediatrician.
Key terms
- Supply Score
- The tracker's 0-to-100 composite output reflecting adequacy indicators including wet diaper count, weight gain rate, latch quality, feed frequency, and session duration.
- Wet diaper count
- The number of wet diapers in a 24-hour period. Six or more per day in a baby past day five of life is the most accessible daily indicator of adequate milk intake.
- Latch quality
- A 1-to-10 self-rating of how well the baby is positioned and attached during feeding. Higher latch scores generally correlate with more efficient milk transfer and less pain.
- Exclusively pumping (EP)
- A feeding approach where breast milk is expressed entirely by pump and bottle-fed to the baby rather than nursed directly. Requires a specific pumping frequency and technique to maintain supply.
Frequently asked questions
Why does the Supply Score not rely heavily on pump output?
Because pump output is a notoriously unreliable supply indicator. Research consistently shows that babies transfer milk two to three times more efficiently than breast pumps, even high-end ones. Low pump output while wet diapers and weight gain are on target is common and does not indicate a supply problem. The tracker weights wet diapers and weight gain instead.
How do I know if my pain level warrants seeing a lactation consultant?
The tracker flags pain scores of 7 or higher with a recommendation to see an LC. Some nipple tenderness in the first few days of nursing is very common. Persistent pain above moderate levels, especially if accompanied by poor latch scores, typically signals a correctable positioning or latch issue. An LC can identify and address these in one to two sessions for most people.
What weight gain rate should I expect after the first two weeks?
The tracker uses a target of 5 to 7 ounces per week through the first three to four months for full-term babies, based on widely cited pediatric guidance. Discuss your specific baby's growth trajectory with your pediatrician. Babies outside typical ranges are monitored individually and the tracker's general targets may not apply.
Can I use this tracker if I am combination feeding?
Yes. Select Combo (breast plus formula) in the Feeding Method field. The wet diaper and weight gain indicators remain relevant regardless of feeding method. The Supply Score will account for the combined feeding context.
