What age did you start brushing your lo's teeth? What brand of toothbrush and toothpaste did you use?

I started brushing baby's teeth at one year old. Using colgate brand for his toothbrush and happy toothpaste for kids. But lately i stopped using the toothpaste kasi nakakain nya. Di daw ok yun. Opted for damp cloth placed on my finger for cleaning baby's teeth.
