What should I do if I notice leaks?

If leaks occur, follow these steps to improve fit and absorption:

1. Check the fit

• Make sure the diaper fits comfortably around the waist and thighs without leaving red marks.
• Pull the diaper up properly and unfold the side elastics.
• Fasten the tabs symmetrically without over-tightening—you should be able to fit two fingers between the diaper and your baby’s belly.
• For baby boys, always point the penis downward to prevent upward leaks.
• Ensure clothing or bodysuits are not too tight, as this can reduce effectiveness.

2. Adjust the size if needed

• Sizes are indicative—you don’t need to wait until your baby reaches the maximum weight to size up.
• Leaks at the back: move to the next size up.

Leaks around the thighs: the diaper may be too small or not properly adjusted.

3. Tips for heavy wetters

For babies with heavy output or baby boys, choose a size with higher absorption capacity, such as T4+ (9–20 kg), while maintaining the fit of size 4.
