Johnny craves ice chips. he used to like ice cubes but since I started giving him ice chips, he prefers them.
In fact, he drinks very little from his water bowl because he's always begging for ice-after meals, after snacks, after his medications disguised in peanut butter.
This may seem like strange questions, but would chewing ice chips help clean his teeth and can they be harmful in any way?
