I am just wondering when do kids start to rinse mouth and spit out the tooth paste? I guess I should probably start getting my daughter to do that now, as she is 2.5 years old! Currently, we just smear a little tooth past on tooth brush (just a small scraping) and brush her teeth and leave it on. But I am worried that maybe I should not be doing this...as she should be old enough to spit now! When did your kids start rinsing and spitting out after brushing?
