Using these baby clothes is super easy. Just dress your little one in them as you would with any other clothing. When it comes to washing, use a gentle cycle and mild baby - friendly detergent to keep the pure cotton soft. Avoid using bleach as it can damage the fabric. Store the clothes in a dry and clean place to prevent any mold or mildew. These clothes are designed to fit newborns, so as your baby grows, you may need to replace them. But they're great for those early days when your baby needs the softest and most comfortable clothes.
