14m old refuses milk, meals and naps in IFC

Hi mummies... my 14m old had just started attending Infant Care, it's her 5th day today. I know it must have been rough for her. She is refusing all meals provided in school and also not wanting to drink milk. She is also not taking her naps at all. It's only better these 2 days, she had a quarter of apple, some cauliflower and broccoli, specially given to her in btw playtimes. Is it normal? I'm getting worried, as i'm going back to work tmr and can no longer fetch her mid noon to feed her late lunch, which she always finishes cause of hunger.
