At my centre the days went pretty much like this:
6am-9am - Cntre open, kids rock up/some toast is put on a table for the kids that didnt have a chance to eat breaaky.
9.30- kids divide into their own rooms ir baby/toddler/kinder ect.
9.30-11.30- structured play indoors or out. They try to get them out as much as possible in the fresh air (when appropriate).
11.30 - hot cooked lunch
12-2pm - sleep time for the little ones have cots or on little mattresses on the floor. Rooms are darkened and realxing soft music is played. Bottles/cups of milk/dummys are given to the kids who have them. The kinder kids go outside, the 3yr olds have quiet rest/reading time. They also accomodate for the babies who have numerous naps during day. Usually cots are positioned in a 'quiet area' up the back of a room for them.
2pm- wake up and do activities
3pm - arvo tea fruit and milk
3.30-5pm pack up/clan up/free play - pick up times start.
5.30pm - a late snak offered to the kids that were still at the centre usually just a bickie and cheese.
6pm - centre close.
Hope that helps
