D.T.
I know it sounds horrible, but I was so nervous about flying with my daughter when she was 18 months old I gave her some chamomile tea and baby tylenol. She was out before the plane took off. This turned out to be a good thing since she did not sleep at all the night before because we stayed in a hotel, and was VERY cranky. I wouldn't worry too much about getting kicked off the plane. As long as your child is under reasonable control most people won't think twice about his behavior. I think the stewardess that kicked that mom off was just a raving b**** with a major case of PMS. Most stewardesses aren't like that. Good luck with your flight!
