Multi-layered bamboo inserts overnight set, 3 pieces. When the night is long and your child wants to stay dry until morning, add an extra insert made of absorbent bamboo fibers to the diaper to increase its absorbency. The insert comfortably conforms to your child's diaper and prevents leaks. The night insert is designed to ensure that your children's nights are filled with colorful dreams. The purpose of the bamboo insert is to absorb a lot of urine so that the child can sleep peacefully throughout the night. This clever insert makes Pop-in diapers some of the most absorbent diapers in the world, and parents love them for it. You can find it in a large, medium, and small diaper set. Additionally, you can purchase it separately if you need extra help during diaper changes. The bamboo night insert is perfectly tailored to fit the smaller pocket in the diaper. Place it as shown in the picture in this pocket. Remember that the smaller insert should be larger than the insert itself to keep the night insert in place.
