Got the cutest Christmas pajamas for my toddler. These are all 100% cotton and Oeko-Tex Certified. Synthetic pajamas are a deal breaker for me when it comes to pajamas. Polyester especially is processed with toxic chemicals that disrupt the endocrine system which is in charge of hormone production. Whenever possible, I always look for organic cotton or cotton material and wash before wear. LTKHoliday LTKGiftGuide LTKSaleAlert
