What is SAP (superabsorbent polymer) in diapers?
SAP is the material inside the absorbent core that soaks up and locks in liquid — it can hold many times its own weight. Higher-quality SAP absorbs faster and resists leaking, but not all cores are equal: SAP-to-fluff ratio, distribution and locking layers all affect performance.
Read the SAP explainer →What is gel blocking and why does it matter?
Gel blocking happens when swollen SAP particles clump together at one spot, blocking liquid from spreading to the rest of the core. The diaper feels heavy and leaks early. Brands fight it with mixed cores, acquisition layers and better distribution channels.
What is gel blocking? →How do I choose the right diaper size?
Match the weight range on the pack (e.g. Size 3 ≈ 8–14 kg). Size up when you see red marks on thighs/waist, frequent leaks despite correct fit, or the tabs no longer reach the middle. Newborn sizes typically last 1–3 months.
Full diaper size guide →Are overnight diapers safe to use every day?
Yes. Overnight diapers simply hold more and use extra leak guards. Many parents reserve them for night to manage cost, but daily use is safe as long as the fit and absorbency match the baby's needs. Always follow the change-frequency guidance.
Are overnight diapers worth it? →What is the difference between diapers and pull-ups?
Tape diapers fasten at the sides and are ideal for newborns and babies who lie still. Pull-ups (pants) pull on like underwear — designed for active toddlers and toilet training. Switch around 12–24 months when the baby starts walking and resisting changes.
Diapers vs pull-ups, compared →How often should I change a diaper to prevent rash?
Every 2–3 hours during the day and at the first sign of wetness. Nighttime can go longer if the diaper holds well. Frequent changes + zinc-oxide barrier cream + brief diaper-free air time are the core of rash prevention.
Change frequency guidance →Which ingredients should I avoid in baby wipes?
For sensitive skin, prefer fragrance-free, alcohol-free wipes without harsh preservatives or dyes. Common irritants: fragrance, alcohol, and certain preservatives. When in doubt, plain water and soft cotton cloths are the gentlest option.
Wipes ingredient safety guide →Are eco-friendly or biodegradable diapers worth it?
They reduce plastic waste and use plant-based materials, which matters to many families. Trade-offs: usually lower overnight capacity and higher price per unit. Good option for daytime when combined with an overnight diaper.
Best diaper lists →What does OEKO-TEX certification mean for diapers?
OEKO-TEX Standard 100 certifies that textile materials have been tested for harmful substances (formaldehyde, heavy metals, etc.) and meet defined safety limits. It is a useful third-party signal, but not the only thing that matters — look at the whole product.
OEKO-TEX explained →How do I choose sanitary pads by absorbency?
Match absorbency to flow: light days and liners for spotting, regular for medium flow, heavy/overnight for nights or heavy flow. Length matters for sleeping positions and leak protection. Fragrance-free options suit sensitive skin.
