I also have been getting my families to do EMTs and biweekly payments as well which has made things easier
Circle time mats
I have special books (sticker, dry erase) that only come out during meal prep. Keeps them busy and at the table those last few mins before a meal
I started serving a lot of the same stuff. I think I felt there needed to be more variety at first but the kids are happy and the parents don't care.
As kids get ready to go outside or I have done their shoes they all know (even the babies) how to get their hats and go and sit on the mat showing they are ready to go outside.
I have a "park bag" that I throw their sippy cups in and it always has a small first aid kit, emergency numbers and of course my sunglasses.
