So sorry you're experiencing this error. We use Webflow so everything is taken care of by them, and it's only happening with a very small subset of users; we're trying to figure out why! Our certificates are testing correctly from a 3rd party tester.

Amazing news! Let us know what you think - our infant sleep experts are pretty amazing! 6 weeks is really tiny, but I am confident our expert will talk you through a developmentally appropriate plan that takes into account your infants feeding needs and sets up on the path for sleep organization! :)
