What you may not completely understand about natural clothing for infants and children, is that they tend to be far better for your child; than synthetically made materials. Natural fibers are considered to be those that are created from plant or animal sources IE: organically grown cotton, wool, hemp, silk, and sometimes even soy, bamboo, and even beechwood that are used to create different clothing. These items are first known as "textiles" that are then created into materials that can be used to make fabric (of which you already know clothing is made from).
However, you may ask yourself; why aren't all clothes natural? Are there really unnatural classified clothing? Well, while some people claim that there isn't any unnatural clothing, it is specified that unnatural clothing usually uses a combination of natural and synthetic materials; including but not limited to harmful chemicals. IE: polyester, nylon, acrylic, and even acetate of which are all petroleum based products. It of course isn't often considered to those who aren't wanting to find a healthier alternative for their children, and the environment.
However it is important to remember, that not all distinctions between unnatural and natural clothing; are simply black and white. Instead, some of the fabrics may fall on a fine line between the two as technically things such as bamboo and tencel may be thought of as man made products. However, they are considered to be a plant and not a fossil fuel (which is processed into some of the fibers). While natural clothing lines will have been processed carefully in their eco-friendly ways, that make it safer for your child to wear. It will of course make it completely essential for you to know, and trust the manufacturer of your child's natural clothing.
One of the biggest benefits to natural clothing, is that it means there are fewer chemicals thrown about the world; and on our children. It is often times said, that natural clothing smells clean rather than of chemicals when first purchased. This is because they haven't been treated with formaldehyde or other hundreds of chemicals used in textile growing, producing, and even the shipping. You may even notice yourself un-able to stand the smell of your normal every day clothes any longer, once you pick up clothing of a natural sort for your infant or toddler. Natural clothes of course might be thought of being drab or monochromatic; while it is quite the contrary as they have adopted a more chemical-free means of producing vibrant and beautiful colors as well as prints for children.
