Features and How to Choose Pull-Up – Big Diapers
A pull-up diaper size generally recommended for children weighing 12 to 17kg, often used from around age 2. This size is commonly chosen during potty training because it is easy to pull up and down. The price per diaper becomes higher at this stage, so comparing online prices can make a meaningful difference in monthly diaper costs. Many families use this size together with training pants depending on their child’s progress.
