The child doesn’t always want to be flexible. Three-year-olds particularly don’t like things moved around. You can help by taking special pillowcases, which you pop onto pillows in airplanes, trains, hotels, and relatives’ houses. You may also turn routine variations into special treats. For example, you’re quite sure the four & five-year-olds will never go to sleep if their eight-year-old sister is in the room, which is how Auntie arranged it. So eight-ear-old sister gets the special treat of staying up with Uncle & Auntie an extra hour!
