Toddler with Covid/ fever won’t take Tylenol!!

id

There’s a huge shortage with Tylenol and Motrin so I got her some little remedies which isn’t sweetened at all. I tried to give it her, she fought and then threw up. I’m wondering if I give her some more right away and what’s the best hack to get her to take some?

Can’t mix it with anything I can think of she hates yogurt and doesn’t have much of an appetite. Pretty worried because her fever is 101.8
