Suddenly not latching

Ha

,Yesterday my little guy spiked a fever for the first time (he’ll be 1 at the end of the month). It was a ROUGH night. I gave him Tylenol and it broke through (The fever is back but not as strong as before) the night but he refuses to breastfeed.. He wanted to, but couldn’t latch. This morning I pumped hoping my milk hadn’t just dried up for some reason and he gulped down 3oz I managed to pump in 5 mins (both sides). Any ideas why he might not want to latch?

He did get 5 teeth in the last month or so but all have cut through and he was doing totally fine before the fever kicked in.

Breastfeeding is so soothing for him and I feel so helpless 😭
