All our nappies are one size fits all, so will last until toilet training and hopefully next bub as well. Very cost effective if you consider the price of sposies. Ours came with extra snap in boosters for night time. Our nappies are bamboo and soaking is not recommended for bamboo hence the dry pailing. Line drying in the sun eliminates stains and is the best defense against germs. You can't use barrier creams with the bamboo nappies as it effects the absorbency.
