Thank you for your response. :) I gave him a little melatonin last night, and it put him to sleep. But he is still having trouble and is also very hyper. Your website states that children under 12 should not take humanatea--he is only 2. Do you think that is OK? I am concerned about how long this symptom might last. I mean, he REALLY REALLY can't sleep. I don't want to have to give him melatonin for too long. Can we be sure that it is not a bad reaction to one of the herbs? Thank you so much.
