I worked in centre care for years and it is part of ministry (Day Nurseries Act)regulations that children rest on their beds for a minimum of 1 hour. I use these guidelines (because they are there for a reason!) in my home childcare as well. After an hour, if the children are awake then they may come up and do a quiet activity or watch a movie but the children are NEVER awake. Because 1) They're little and kids need more sleep than we do and 2) I keep them so busy that they are tired! You can't force a child to sleep if they are not tired. My little man is 3yrs old and naps for 2 hrs per day (I wake them at 3 if they are not already awake) and he goes to bed again by 8 at the latest each night, tuckered out because I keep them busy all evening as well
