HappyBear's microfibre boosters can absorb approximately 150 ml of moisture, which is more than most boosters from other brands.

For your newborn baby, a microfibre booster in your HappyBear pocket diaper is sufficient, but you will soon find that you need more boosters. For example, you can combine a microfibre booster with a bamboo booster or a hemp booster.

Make sure the microfibre insert is on top, as this booster can absorb moisture faster than bamboo. A bamboo insert can retain more moisture.

Make sure that you do not place the microfibre booster directly against your baby's bottom, but put it in the opening of the pocket diaper.
