Does our 2 layer bamboo flat not quite meet the needs of your VERY heavy wetter? Need a little something extra to get him or her through the night? Our 2-layer bamboo booster is a great way to bump up your system's absorbancy. Wrap it in a 2-layer flat 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!
