My request seems to be ignored. I have also experienced migraines in the past and I am not happy with him drinking coffee. Please let me know if you have any information on coffee, being bad for children etc. Caffeine is a stimulant. It can cause increased heart rate, increased blood pressure, irregular heart beats, nervousness, anxiety, insomnia and an increase in stomach acid.
Caffeine is also addictive and withdrawal can cause headaches, lethargy and depression.
The average cup of coffee contains 80 to 150 milligrams of caffeine. 40 milligrams per kilogram of body weight is toxic for a child. High doses can cause delirium, disorientation and seizures. Another problem with coffee is that it contains acids that are hard on the stomach. The acids may cause stomach pain and acid reflux or heartburn.
