Dear Amy: My husband and I have two boys, ages 7 and 4. The 7-year-old is a great traveler, but the last time we flew on a plane, when he was 5, our older son completely freaked out. I think the sound of the engine and the motion of the takeoff and landing scared him. He was fine once we were in the air, but to this day he says that he never wants to fly on a plane.
