Your kid is just 14 months, don't worry too much for the time being. Your kid might not ready to understand what you are doing.
Show him/her how to brush your teeth ever morning and before bed so that to make her understand that is a routine have her own brush ready at the same time so that whenever she started to have an interest to try on her own, gear is ready (do forget to praise her when she starts doing it). Play her VCD as well. I've noticed that kids tends to copy from VCD rather than us.
