Both our Pre-folds and Flats are made of GOTS (Global Organic Textile Standards) Certified Organic Cotton. The Organic Cotton is sourced from India, they are super absorbent, absorb really fast and also dry fast after wash. Cotton is anti-bacterial by nature. It is the most healthiest option for the baby. Cotton tends to get stiff when dried in sun. Dry it in shade for a softer cotton. Sun dry them as and when possible. It is a natural disinfectant and the stains just vanish. Do not use any rash cream. A good essential oil like Virgin Coconut oil will do wonders.
