Karlene, My friend has four year old twins and they hate doing both brushing their teeth and their hair. First we use a good conditioner on their hair when they are in the bath tub and I bought some kids (leave in) - no tangle spray. We wet their hair with a spray bottle (if they didnt just get out of the bath) and then spray in some of the no tangle conditioner stuff and then brush it, sometimes you have to use quite a bit of the no tangle stuff to get it to be tangle free but at least its good for their hair. One of the girls said that it made her head itch, we figured she maybe had a sensitive scalp so we tried a different kind and she was just fine. Also try using different kinds of brushes. About the teeth, we explain to them that they have to get the sugar bugs out so their teeth dont get cavitys, then if they brush out all of the sugar bugs they get to use the very yummy kids floride mouth wash. They look forward to the bublegum flavored mouth wash.
