Features and How to Choose Tape – Extra Small Newborn Diapers
A smaller newborn diaper size designed for babies weighing under 3,000g. This size is suitable for premature babies, low-birth-weight babies, or newborns who are too small for standard newborn diapers. If the waist is too loose, urine may leak more easily, so this size is often used only for a short period until the baby gains weight. Since the usage period is usually brief, avoid buying too many at once and switch to standard newborn diapers when the fit and weight are right.
