Landismom is a good problem solver:
When it started to get cold this winter, my three-year-old son kept waking up in the middle of the night. We turn our heat down after everyone goes to bed, for environmental and money-saving purposes. He kicks off the blankets in his sleep–we re-cover him when we go to bed, but with his short hair, he’d get cold early in the morning and wake up waaaay too soon. I started making him wear a knit cap to bed, like when he was a baby, and he’s back to sleeping through the night.
