Anyone in my daycare lays down on a napmat for at least an hour. 9 out of 10 days they fall asleep in which case they stay obviously. I will get up anyone that has rested properly and let them look at books, colour, or do quiet games at the table. I get an hour where I am not responsible so to speak. Even once they are up they are on their own as in I am not available to get them anything other than what I put out for that day. Any misbehaviour and they loses the privilege of getting up the next day.
