I don't do an am snack until 9:15 - 9:30. My drop off's vary from as early as 7am and as late as 9am. So there is lots of free play until everyone is here. Then a quick good morning circle time and off to the snack table. Then it's outside or craft (or both on some days)

I guess I'm lucky, the only food that my daycare kids show up with is toast. I had one have a timbit once in the car, but that was because when mom came to drop off my drive was full with another client so she chose to go get her coffee first and ended up getting a tim bit for the little guy, he finished it in the car.

I have some fatal allergies in my home so I'm very careful on what comes in and what stays out.
