Not car sickness, food from McDonalds or eating too much. Eating and then standing on her head is a possibility, but I would think that would make one throw up once, not all through the day.
I asked Mom what she’d had to eat and she said she didn’t know. That confused me for a minute. Then I realized she goes to preschool half days, so maybe it was something she ate at school. Maybe orange juice and milk, as @kritiper suggested. Or maybe poisoned graham crackers.
Anyway, she hasn’t thrown up today and she’s eating OK, so whatever it was appears to have worked its way out.
I may go see her later.
Kids.
