My 5 month old has a fever and I keep trying to give her infant Tylenol help

Kayla • Mommy to two beautiful little girls

She keeps gagging on it when I put some in the side on her cheek with the syringe I barely put it in her mouth so I know I'm not putting it too far down her throat. I tried squeezing her dose into a nipple of her bottle and try to get word to her that way she won't eat it that way either it's grape Tylenol she took some last night and she threw up the little bit she got can I mix it with her formula or anything in order to give it to her first time mom here
