1. How many washable nappies should I get for my baby?

On average, full-time use requires 20 to 25 washable diapers with washing every 2 to 3 days.

This number varies depending on several factors:

  • the baby's age;
  • the type of layer used;
  • the drying time of the inserts;
  • your exchange frequency.

2. Signs that a diaper needs changing

  • the diaper becomes heavy or swollen;
  • an odor appears;
  • baby seems uncomfortable;
  • The first signs of redness appear.

Changing the diaper regularly helps to protect baby's skin and prevent leaks.

3. Risks if the diaper is changed too late

  • moisture-related irritations;
  • persistent redness;
  • disturbed sleep;
  • end-of-capacity leaks.

Having a sufficient stock helps to avoid waiting too long between exchanges.

4. The different types of washable diapers

  • TE1 — an all-in-one system that is simple to use but takes longer to dry.
  • TE2 — separate inserts, quick drying and adjustable absorbency.
  • TE3 — modular system with gondola.
  • Classic — very absorbent, often used for nighttime.
  • Pre-flat — very quick-drying textiles.
