Features and How to Choose Tape – S Diapers
A tape diaper size generally recommended for babies weighing 4 to 8kg, often used from around 1 to 4 months old. Tape diapers are easy to change while the baby is lying down, making them useful before the baby can hold their head up. Since this is a stage with around 8 to 10 diaper changes per day, cost performance is also important. If your baby starts moving their legs actively and the tapes come loose more often, it may be a sign to consider pull-up diapers.
