What would you do - child shows up at snack time

[adorable ages]

Hi. I can say from both sides, caring and parenting, I always ask the parent, or always in turn tell the care giver if my child has eaten enough to last till the next snack/meal. No matter the age or ability to know the difference the child should be directed by an adult to ensure proper nutrition. Perhaps just flat out ask on their next drop off, has your child been fed yet..? Good luck
