Lok for fluride free
It is good to get in and start working on baby teeth before they get attitude( & refuse to cooperate).
Under 3, we like to avoid fluride containing products. Babies need to learn to spit these out rather than swallowing them & building up xs fluride in their body. Baking soda was a common standby years ago but is a bit abrasive. There are dozens of baby toothpastes avaiable under many brand names.
