I have to struggle with difficult child to get him to brush his teeth. Complains of the after taste and stays with him all day, yada, yada, yada. A friend who has similiar struggle said she bought Lemon or Vanilla toothpaste and her son now brushes without that complaint. She said Crest makes it. I can't find it. Has anyone ever seen it or have the similar experience? difficult child now won't drink milk. Not even chocolate, which he use to. Gives him a bad taste.
