At Woohoo NANA we are working towards a reusable future for our home and yours. Our products are here for you to use time after time and if you wish you can pass them on. Such as our toilet training undies, nursing pads. We use fabrics that are friendly to our bodies. All products are cotton topped with a bamboo fleece core. We do use PUL to dry proof all products. PUL is man made but is the best option for our products. Our products are here to help you on your way to a plastic-and chemical free future.
