No constipation, and I'm not sure the eczema was sudden, he's always had dry bits here and there, so it could just be the weather? He slept great last night too so I'm hoping it was just bad teething and all the other things were coincidental.
There are milk sensitivities in my family but no food allergies on either side. I'm really hesitant to stop feeding him solid food since he's having fun with it and we just started. We haven't given him anything to crazy but maybe I'll just keep track of the food and how he's sleeping.
