Pañal

The cover is the waterproof outer shell with snap adjustments for fit, worn over an absorbent insert or liner placed inside. Covers can typically be reused for a few changes if not soiled, while inserts are swapped and washed after each use since they hold the actual wetness.

Microfiber inserts absorb quickly but can compress and leak under pressure, so they work best for daytime use. Cotton inserts hold more liquid and are gentler against skin but take longer to dry. Bamboo charcoal inserts are prized for odor control and high absorbency, making them a popular choice for overnight use.

A common starting point is 15 to 20 covers with 20 to 30 inserts, which allows for a wash cycle every 1 to 2 days without running out. Newborns who change more frequently may want a slightly larger stash than an older, more established toddler.

Most cloth diapers are machine washable: a cold rinse to remove waste, followed by a hot wash with a cloth-diaper-safe detergent (avoiding fabric softeners, which can reduce absorbency), then air-dry or tumble dry on low. Follow the specific care label for covers and inserts, since materials like bamboo charcoal may have slightly different care instructions than cotton or microfiber.

No — swim diapers are designed to contain solid waste in the pool, not to absorb liquid the way a regular cloth diaper does. They're reusable and waterproof, but shouldn't be used as a substitute for an absorbent diaper outside of swimming.
