How do you tell if your baby has an ear infection vs. just discovering their ears?

Baby girl had runny poops yesterday and today has been fussier than usual and grabbing at her right ear.

But... when we give her something to do, shes no longer fussy.

Husband thinks we just need to clean her ears. And I really don’t want to have to take baby girl to the hospital on Christmas for an ear infection 🥺 (obviously I will if I need to)

So, what are some sure signs of it? Or does this sound like it?
