I just noticed DD was shivering. It is cooler her recently, but the room is comfortable and she's got a blanket. I just felt of her back and she feels a little warm, but I don't think it's a full blown fever. She's been teething the past few days, but has gotten over the roughest part of it. Could she still be feeling a little wimpy from teething? I haven't noticed any other symptoms, but I'm keeping an eye on her tonight.
