I sometimes stop into a Starbucks with my 10-year-old son, my 19-month-old daughter, or both. Generally, they stick to water and cookies or water and a piece of cake. My daughter seldom drinks anything but water or milk, and my son's worst vice is lemonade (which is actually really bad for his teeth, what with all the acid and all). Henry, my son, actually asked to try a sip of my coffee at home and I allowed it. He seemed to like it, but hasn't repeated the request, so hopefully I'm in the clear.
