Any tips on giving a 8 month old medicine (infant Tylenol)?

She use to take it just fine from a syringe but now she’s fighting me like crazy. She doesn’t get Tylenol very often but she’s been teething badly this week and that’s when I started having a hard time.

She’s breastfed so doesn’t have a bottle daily but she does drink water from a straw cup. I’m worried she won’t drink the water at all if I add the medicine to it.

Anyone have trouble with giving meds in a syringe? What worked?
