Some kids get diarrhea others get low-grade fevers but all get irritation, irritability, restlessness and inflammation of the gums. There are a few product out on the market the soothe the discomfort of teething but most, like Baby Orejel, numb and harden the gums which is a discomfortable feeling in its self.
I came across Humphrey's with my oldest son Christopher, he never fussed while giving it to him like he did when I gave him Baby Orejel so when Carlos started teething I knew which product to go straight to. He started with the palettes, which dissolve in a spoonful of water, and now he upgraded to the strips which dissolve straight on the tongue and he loves them lol. You can get these at any drugstore, grocery store and the be all of baby Babies R' Us.
Hope this helps if you have a teething baby in your hands :)
