High temp in 8 week old! Help!

Kimberly👩🏻👨🏾👧🏽👶🏽

My baby is running a temperature of 100.1 but has no other symptoms. I took her temp because the ac went out and I'm trying to make sure she doesn't overheat. Any advice would be helpful. Should I take her to the ER or would that be me overreacting?

Update:

I was able to cool her down. The house was just too hot for her. Taking her to the pediatrician tomorrow for her 2 month check up.
