Features and How to Choose Overnight Pull-Up – Big Diapers
An overnight diaper size generally recommended for children weighing 12 to 17kg. This size is often chosen for 2- to 3-year-old children who are potty training but still need diapers at night. Many families use training pants during the day and overnight diapers only while sleeping. Because overnight diapers have higher absorbency and a higher price per diaper, comparing prices before buying is recommended.
