From the age of about 2 1/2 they start to develop a vivid imagination and some result in nightmares.
Younger than that, sometimes their sleep pattern goes out of whack. I know of one little toddler who took on waking up at pretty close to 12.30am every night. You could almost set the alarm. In desperation they took her to the Dr. for a checkup. After extensive tests the Dr. came to the conclusion about the sleep pattern. They gave drops for about a fortnight. As soon as she showed signs of sleeping through they weaned her off them even though they had been told to give them to her for longer than that.
