Since babies have delicate skin, you want to pick something that is comfortable, soft and hypoallergenic. Both bamboo and organic cotton fabrics meet these requirements. Bamboo is a renewable resource and grows naturally without the need for fertilizers or pesticides. Organic cotton also does not use synthetic fertilizers or pesticides that can be harmful to your baby’s health. Bamboo fabric is incredibly soft and often compared to cashmere. It is highly absorbent, naturally odor-resistant and very breathable which is great to prevent your baby from overheating. Organic cotton is durable, highly absorbent and also excellent for sensitive skins. Both fabrics are excellent for swaddling or as lightweight blankets/stroller covers with the main difference being the hand feel. Our favorite is our 70% bamboo and 30% organic cotton swaddles because it has the best of both worlds!
