Features and How to Choose Overnight Pull-Up – M Diapers
An overnight diaper size generally recommended for babies weighing 6 to 12kg. Compared with regular M pull-up diapers, overnight diapers are designed with higher absorbency to help prevent leaks during long sleep periods. They can reduce nighttime diaper changes and support better sleep for both babies and parents. A common approach is to use regular pull-up diapers during the day and switch to overnight diapers only at night.
