I love these! My little guy started teething at just one month old... yes, at four weeks, breastfeeding started to really hurt all of a sudden and I couldn't figure out why until I realized that he actually had a little tooth poking out of his top gums. Holy moly!! Was I surprised or what? I called my midwife and she recommended Hyland's teething tablets. I went right out to the store and bought a bottle. I was a little worried about putting a tablet into the mouth of an exclusively breast fed infant and thought perhaps he might choke, but those little suckers dissolve really quickly, so no worries there at all. They have a little something to help calm him and help him sleep and they relieve his pain just enough to calm him too. Awesome.
