Includes the bambam fitted nappy outer and inner bambam booster To fit 2.6lb - 17.6lb (3 - 15kg) How bambams work Bambams are a fitted cloth nappy specifically designed to fit every single newborn no matter how small they are! Made from 2 layers of thick and lush bamboo terry means the whole nappy is not only super absorbent but it moulds to fit a newborn perfectly. So perfectly, in fact, we guarantee it! Bambams close with a snappi giving a much better fit than a snap or touch tape closure. If you aren't a fan of snappi's that's ok, when your baby is young they don't move around very much so you can use the cover to close them. As Bambams are fitted nappies they do require a cover, we recommend using one of our PUL Gusseted Covers as the perfect combination. A fitted nappy and a PUL gusseted cover will contain anything your baby can throw at it!
