Okay. We just saw that my 4 mo son has a ton of white gunk in one ear (originally about double what's in the picture). It's all dry and flaky and crumbles as I swipe my finger. He's acting normally, eating normally, no fever, no ear pulling, no recent illness.

We did recently start going to daycare, where he was today. They didn't say anything about it but maybe spit up or milk?

Call ped tonight? Wait and call ped in the morning? Ask daycare in the morning? Not worry about it, if he continues to act normally? Go to urgent care?
