Bio-Baba nappies are made in South Africa using cotton and hemp, and are one of the most versatile cloth nappy on the market - being used for everyday nappies, night nappies, swim nappies and potty training. They are an all-in-one product, so no separate time-wasting procedures when fitting ie. dealing with a liner, then the nappy and then the waterproof. With Bio-Baba it is all fitted, with a flip out flap to get rid of the 'good stuff'. Bio-Babas have 'smart-fit tabs' which protect the Velcro during washing so that it does not pick up lint, which is a real problem in other cloth nappies as the Velcro no longer sticks properly after a while. You do not need to change the nappy nearly as much as normal cloth nappies as hemp really is super absorbent. Bio-Baba has a breathable outer, making it cooler for baby and less likely that bacteria will grow and cause a nappy rash. The Bio-Baba nappies don't have a PVC waterproof which is a plus, as PVC is not "green" friendly.
