Baby's urine volume: measuring, understanding, and adjusting your cloth diapers
Quick summary
Urine volume directly affects the performance of cloth diapers. By measuring it using weighing, the syringe test, or observation, you can adjust absorbency, prevent leaks, and optimize your baby's comfort. This guide details average volumes, reliable methods, and the most effective insert combinations.

Why measure a baby's urine volume?
Urine volume plays a major role in the performance of a cloth diaper. A baby who urinates frequently can quickly saturate an insert, leading to leaks due to overflow or compression. Measuring this volume allows you to adjust the absorbency and precisely meet your child's needs.
Methods for estimating urine volume
1. The weighing method
Weigh the dry insert, then weigh it again after use: the difference in grams equals the milliliters of urine. This is the most reliable method.
2. The syringe test
Add water gradually to a clean insert to identify its actual maximum capacity.
3. Observing the rhythm
If a diaper is saturated in less than an hour, your baby probably has a high urine output.
Average volumes according to age
- Newborn (0–3 months) : 100–300 ml/day
- Baby (3–12 months) : 300–600 ml/day
- Toddler (1–3 years) : 600–900 ml/day
These volumes vary depending on hydration, temperature, and diet.
Adjust absorption
For a small volume
A thin insert like the Doux'Plis is often sufficient.
For an average volume
A Bambelis Trifold + a lightweight booster offer a good balance of speed and storage.
For a large volume or at night
Combine an Absorb6 with a DouxBoost for long-lasting absorption.
Common mistakes
- Stacking too many inserts: risk of compression.
- Forgetting to boost the volume at night often doubles.
- Laundry detergent that is too greasy: clogged fibers = reduced absorption.
- Confusing leakage and saturation: the two are similar.
FAQ – Urine volume & washable diapers
How can I tell if my baby is urinating a lot?
If the diaper is soaked in less than an hour, it's a sign of a large urine volume. Weighing remains the most reliable method.
What absorption rate should I expect for the night?
Nighttime urination is often more frequent. An Absorb6 insert plus a booster ensures optimal absorption.
Does concentrated urine damage the inserts?
They can damage the fibers if they stagnate. A thorough rinse helps preserve absorbency.
Which combo should I choose for a big pee?
Combine modal (speed), bamboo (storage) and hemp (retention) to prevent leaks.
Conclusion
Measuring urine volume allows you to precisely adjust absorbency and prevent leaks. By understanding your baby's needs, you optimize the comfort, stability, and effectiveness of your cloth diapers while reducing their environmental impact.
