I'm not a parent, but when I was little I hated brushing my teeth. In fact, I would do it without toothpaste, just so that I could tell my parents that I had brushed them. Most of the time, the flavour was too strong for me to handle. The toothpaste that I use now is the Crest clean mint/smooth mint. It has a little bit of a softer, but still minty taste and it's also spearmint, rather than peppermint (which tends to taste stronger to me).
