While many might think it typical and healthy for a preschool child to take naps, in recent years, the preschool nap has been called into question. Preschool naps are being removed from the classroom to make time for additional directed learning, and some researchers have suggested that naps diminish nighttime sleep quality. However, my research has shown that this may not be true. I aim to better understand the function of the nap in preschoolers, and how the nap may influence nighttime sleep.
