Well i couldn't wait for RNW so bought one from FYP last week have been testing it out...on my heavy wetter it will last roughly 3 hours before we get wicking and leaks on her leggings...and that was boosted with one little lamb bamboo. (size 1)
I did try 2 ll bamboo but DD did a huge poop in it before i could see how long it lasted
will be boosting with a charcoal bamboo booster next as i happened to find one today, lurking in the nappy box!
I have bought 2 more in the RNW offers as 3 hours for us is pretty good and they are a good fit on my 20mth old. (still didn't stop me buying more flip organics and some of the new colour flips wraps though
