My son has been cutting teeth very fast and he popped out 6 teeth within a week and he was non stop crying and miserable. I ordered this as nothing I used was working. Within 30 minutes of using the roller on his jaw line, he became a lot calmer. Still very miserable but he was easier to settle and even slept a lot better once we started using it. Highly recommended! This picture was taken 20 minutes after the first use!
So far have used once and it has seemed to help relieve teething pain. Easily to apply even with bub squirming. Definitely recommend if looking for a more natural relief
