Does our 2-layer rayon from bamboo insert not quite meet the needs of your VERY heavy wetter? Need a little something extra? Our 2-layer rayon from bamboo/organic cotton booster is a great way to bump up your system’s absorbency. Wrap it in a 2-layer insert and you get a total of 8 layers right where your baby needs it! Fold it in half and place in the front of the diaper if you have a boy for extra absorbency right where he needs it!
