2 year old throwing up

She’s usually a big eater and hungry all day. The throwing up started after eating a cereal bar for breakfast this morning. She’s thrown up 5 times since. She did ask for food and eat a 1/4 piece of bread like 15 min after the 2nd time she threw up. But I think that was a bad idea, she threw up like 20 min after that

She just took an hour long nap and hasn’t thrown up for 2 hours now. I think she’s still getting nauseous tho.

I’m not sure what to do about food? Would you feed her anything for dinner? She’s picky lately so she wouldn’t have broth or anything like that. Should I be limiting her fluid intake at all?
