Features and How to Choose Overnight Pull-Up – L Diapers
An overnight diaper size generally recommended for babies and toddlers weighing 9 to 14kg. Unlike daytime diapers, overnight diapers need strong absorbency because diaper changes are less frequent while the child sleeps. Demand for this size often increases around age 1, when children may begin sleeping longer through the night. Although overnight diapers cost more than regular L size diapers, they can save time and effort by reducing leaks, clothing changes, and bedding laundry.
