Hi.. My son 2.1 yes.. He always eats toothpaste and never allow me to brush the teeth and he doesn't know to spit out.. He simply bite the brush until paste s over.. Hardly a brush ll last for a week as he bites the brush and the bristles ll be out of place.. Can someone help with me the techniques and ur worked out strategy for brushing.. Also brushing without spitting is safe? I m using fluoride free paste..
