My almost 19 month old daughter has basically flipped a switch the past few days, she's AWFUL to deal with. Almost everything is a fight and today she threw an epic 1+hour long tantrum after she woke up over nothing. She has some clear runny nose, but I can't tell if she has any teeth coming though. What did canines look like for you? I hear they are the worst over anything. I'm hoping it's teeth and not her changing into this from the sweet girl she was before.
