The little guy finally napped for an hour today. It's his longest (and sometimes only) nap since Friday.
The mouth sores are "the worst" our pediatrician had ever seen. Since Eric has only eaten about a half cup of cool oatmeal for the last 48 hours, I was not surprised. I have tried offering him anything cold. He has free range in our freezer, but now he's not drinking much either. I found out why last night and had it confirmed today at his appointment- Eric's 2 year molars are coming in.
Either Eric did something horrible in a past life, or I did.
