I teach older 2s through young 4s, at least that is my spread this year. The majority of my class have just turned 3. I'm considering offering snack as a center rather than having a separate group snack to avoid more transitions as well as to lengthen play time. Does anyone have any experience with this? I can't find any written guidance on this from the State of Virginia from a food safety issue. So I'm interested in that, but also if anyone has tried this model and how it worked. Thanks.
