Thinkbaby continues to lead in the usage of safe materials for baby products. It all started when the brand found out that 95% of the bottles on the market were composed of Bisphenol A (BPA), a chemical that is suspected to disrupt the endocrine system. From there, the brand came up with alternatives that were safer, more functional and more sustainable. All of the baby bottles are made from No. 5 plastic and can be recycled. When the brand built its Complete BPA Free Feeding Set, it lined the products with stainless steel, making everything last for a very long time. The brand then proceeded to target other products within the baby feeding realm and were led by parents to design a sports bottle--a line called Thinksport.
