About The Brand

With a team of physicians and scientists focused on the latest chemical and biological science, Thinkbaby continues to lead in the usage of safe materials for consumer products. Our efforts are further energized by working with both our leading child advocacy partners and like-minded individuals who seek alternative products. We look to make our products sustainable. And we do this in two ways: either the product needs to have an extremely long use life or it needs to be recyclable. The truth though is that we try to do both.
