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!
