This is our third baby to use Spiffies at the recommendation of our pediatric dentist. Our baby loves the flavor and looks forward to us using the Spiffy. She is currently 9 months old. With strict supervision, we often give her the Spiffy while we are changing her diaper. It keeps her from wanting to crawl away, takes care of dental hygiene, and lets us see her sweet smiling face all at the same time. We never got into a good routine of cleaning our firstborn's teeth as an infant (he turned out fine dental wise, no cavities yet at age seven), but using Spiffies has made it easier to fall into a routine daily dental cleaning with babies two, three, and four.
