Features and How to Choose Pull-Up – S Diapers
A pull-up diaper size generally recommended for babies weighing 4 to 8kg, often introduced from around 4 months old when babies begin sitting with support. This is commonly the first size used when switching from tape diapers to pull-up diapers. Pull-up diapers are easy to change whether the baby is lying down or standing, and a snug leg fit helps prevent leaks as babies move more. Once crawling becomes active, pull-up diapers are often easier to use and stay in place better.
