Boosters are a great way of adding extra absorbency to the nappy if required during the day or at night. Place them inside the nappy on top of the absorbent lining. Our boosters are super slim, yet super thirsty, so you can even fold them or add two at a time. If your baby is a boy, use them to add extra absorbency to the front of the nappy, for girls add them closer to the middle. During the night, using boosters is particularly important as they offer the absorbency required for this prolonged period of use. If your baby drinks a lot before bedtime, we even recommend using two boosters.
