Is it too early for six year olds to be drinking coffee? Naaalala ko yung first time grandmother let me drink coffee and I was maybe five or six.

Consistently? Or just tried it once? I don't think kids should be exposed to more than 45mg of caffeine a day. Despite the rumors that it stunts growth, research has proved otherwise. In any case, caffeine causes jitteriness/nervousness, upset stomach, headaches, difficulty concentrating, difficulty sleeping, increased heart rate, and increased blood pressure....all of which are things you probably don't want to expose kids to. If it was just once, though. It won't cause any longterm damage or anything. http://kidshealth.org/en/parents/child-caffeine.html
