Normal or not moms?

So my baby girl ended up getting a fever of 101.6 the highest 101.7 on Saturday morning. We have her infant Tylenol the fever would go down by a lot 98.7, but come right back a few hours later. Well today is Monday and she has gotten a fever since 4:30 pm yesterday. Now she’s just refusing to eat. The last time she fully drank her formula was at 1:30 AM. It’s now 2:00 PM she’ll eat teeny tiny bites of a kolache, drank some water and some gerber puffs. We’ve never had a problem with her eating till now. Is it possible that’s it’s just because she’s teething or because she’s just getting over being sick. When she had the fever she would drink a little more by now. I believe a molar is coming in and I heard those are the most painful. She just turned 1 today! ❤️
