Natural materials act as barrier against toxin exposure; for instance, many commercial nursing pads contain industrial bleach and other heavy metals that can be toxic when exposed directly to skin. On the other hand, organic versions of pregnancy wear are usually made from bamboo or cotton which is hypoallergenic and free of harsh chemicals. This not only keeps the mother safe from harmful toxins during pregnancy but also minimizes the risk posed during delivery too by cushioning baby from any potential impacts. Aside from comfort and convenience, natural materials also provide comfort for both mother and baby!
