I used to work at a daycare/preschool setting where several of the teachers (almost regularly) fell asleep in the classroom during nap time. It was disturbing to me, but the other classroom teachers did NOT leave the children otherwise unattended. It's not fair to make the other teachers take the responsibility when that time (not on break) should be spent prepping. On the other hand, after a car accident 2 1/2 years ago which has made a full night's rest impossible for me, I totally understand the feeling of needing a nap, especially with my current sweet but VERY demanding class of 3's and 4's. They can be exhausting. (I work 7:30am to 4 pm!) However, I chose this profession and LOVE IT! I need to rise to the needs and my own expectations for my class. Someone who sleeps every day and yells at their class is burned out and needs to consider a new job. Preschool and daycare can be exhausting and strenuous but SO important to the children's future and well-being. Someone who yells is not setting a good example and sets a neative tone for the classroom.
