Nature Babycare nappies and products are really good. They fit better than market leaders, are cheaper, and are at least a little better for the environment. They are made in the best way for the environment possible, without using chlorine bleaches and with pulp from renewable sources, and are 70% bio degradable, although of course they do still go to landfill.
They make both nappies and pull ups, as well as chemical free degradable wipes, and nappy sacks
They are obtainable at Sainsburys, Waitrose and bigger Boots stores.
