Is this weird? Daycare

I run daycare from my home. Currently I have a 10m old little girl between 5-7hrs twice a week. She is breastfed and eats a little bit of solids ... her parents send her with only water, everyday. No milk, no formula, nothing. They are very well aware that I do not supply those things. Is it just me or is that just weird!?! My daughter is 21m and I still breastfeed so obviously I smell like milk and it drives my daycare kid crazy.
