I can't believe a hoemopathic product this good exists! 15-20 minutes after taking baby settles down and feels noticeably better. They seem expensive but you only need to use 5 drops per dose in babies which means that you get a lot out of one vial. The adult dose is a full vial to put it in perspective. These are an excellent remedy for use in children, especially young babies for their first few colds and ear infections. They are recommended for use during infections with or without fevers. I wish I'd found these sooner but am relieved to find an alternative to soothe baby rather than Tylenol.
