i have just received my first fittle BBH nappies so they are on the line drying, but what i have hurd is that the bamboot fitted one are really great and there was a mom who's son was a hevvy wetter he actually wet huggies so bad that it started to leak but she changed to BBH fitted nappies and say's that it is much better than the desposables, and to be honest it have to be done to wet huggies so bad that it actually leak. so that says allot of BBH fitted bamboo nappies. the BBH fitted nappies are not very bulky and personal oppinion they are actually slightly trimmer than the all in one BBH nappies, but i have a couple of all in one BBH nappies and they do not absorbe that well but that is also saying that i do not have it in the bamboo so i think that the bamboo one's in the all in ones will absorbe more than the other one's. i will keep you posted on what i think regarding the absorbency on the fitted BBH nappies. so keep watching the space.
