i used wet hanky to clean his tongue n gums since 1st day home. finger brush (w/o toothpaste) since he has 1st teeth. finger brush with toothpaste when he was around 13-14mth old. kiddy tooth brush with toothpaste after 2-3 mths later.. he is alrdy 2, he know hw to brush his teeth but only able to brush the back ones, usually i will let him brush 1st, after that i brush for him again, esp the front ones cos he still dont really know how to. i think it is always good to start tooth brushing habit since young. those kiddy toothpaste are safe for kids too..
