The most common crib bedding fabrics include:
Cotton is a soft, durable, and breathable fabric. Organic cotton is even better since fewer chemical are used to process it, reducing the risk of allergic reactions or skin irritations. Cotton is particularly preferred in the summer, because it keeps the baby cool.
One problem with a cotton sheet is how much it wrinkles when laundered. You can iron it, if you must, but actually, when the sheet is pulled tight across the mattress, many of the wrinkles get stretched out.
Linen is a natural fiber that is absorbent and breathable. Your baby stays dry and comfortable throughout the night. Linen is also hypoallergenic and does not let bacteria, dust mites or other germs to build up.
When they are new, linen sheets are thicker and coarser than other fabrics. Sheets with a higher thread count are softer, but very expensive.
Polyester is a synthetic fabric less expensive than organic cotton or other natural fabrics. There are satin, microfiber and chenille polyester sheets that are soft and durable. They wash beautifully and without the wrinkles.
Polyester is not as breathable as cotton; you may want to save the polyester sheets for winter.
Bamboo is catching up to cotton in the “most popular sheet fabric” competition. It is the choice of parents who want an eco-friendly, natural fiber. Bamboo is hypoallergenic as well as comfortably soft.
Bamboo sheets are not as durable as cotton, linen and polyester.
Flannel can be made from cotton or polyester. The sheets are strong, soft, cozy and lightweight. Flannel sheets retain heat, so are ideal for the baby born in the winter.
