This product is actually too good to be true. The past month, especially the last two weeks were terrible because my 3.5 month old was in a constant state of irritability, discomfort and just overall misery. We gave this a try because my mom gave it to us and said it was worth a shot. Within literally 15 minutes of having this, her whole demeanor changed! She stopped fussing and slept great that night. We are still surprised, but have been using this for the last two days and have our angel back!!! For every parent who is at all suffering with a baby suffering through teething this is a MUST try! We just hope it keeps on working!
