Also just wanted to add you do not need to 'give up' a portion of your program in order to offer a snack period ... remember that outside time is RIPE with programming options too - we often do creative exploration and sensory outside and when weather is nice I do EVERYTHING outside including circle/story time under the tree on a blanket.

If you are standing at the bus stop 'waiting' for the kids to get off the bus - you can do a circle time there ... I have finger puppets and books packed in my back pack and when we take 'bus field trips' I do a circle time while waiting for the bus so the time passes quicker and they do not get 'silly' while waiting.
