Daycare - Masks... bottle issues

So, my babies (4 year old and my June baby) started daycare this week. Teachers are required to wear masks. Kids are not wearing them at all. My children have not been to daycare since early March. My baby is having a hard time transitioning back to school. She won’t nap (she’s there from about 9-3) and hasn’t drank a drop from her bottles. She’s eating her purée food just fine. Any ideas of what I can do to encourage the bottle eating? Idk if she’s scared of the masks... working on transitioning or what. I’ll take all ideas.
