Which side did Ivy wake up on?

Our daughter Ivy has a very unique personality, she is a very sensitive, dramatic, expressive, sweet, caring, confident little girl. She is very helpful and independent, she loves to do things all by herself. But she has been going through quite the phase lately! Now Ivy is a morning person, more than anyone else in the family. She wakes up very cheerful, she looks forward to her cereal and pineapple juice. After breakfast she watches a little Dora, then it is off to play dress up for the rest of the morning. Later I make her a healthy lunch while we talk about princesses and witches. After that, it is time for her nap. Now I know that most toddlers hate naps, but not Ivy, she likes them. I think most 3 yrs olds' get pretty cranky and fussy before their naps, that is why the nap is needed, because they are tired. But Ivy goes down so easy! This is where the "phase"comes in. I will be cleaning upstairs or feeding Cole or doing something constructive (like always) and all of a sudden I hear this screaming! I ran downstairs the first time I heard it because I thought Ivy had fallen off her bed but now...... now I just wait for her to come to me. She is soooooo moody! Aren't naps supposed to help this behavior? She turns into quite the angry little girl. I don't know what it is, you would think after a nap she would be happy and refreshed, ready to play some more, but noooooooooo.... that is not how it works in this house. It is pretty funny to listen to this mad girl stomping up the stairs screaming... but it is also quite ridiculous! So I am not sure what to do or why this is happening, but I took some pictures to show what I am talking about.This is right before nap time...








And this is right after nap time. Wake up on the wrong side of the bed did we?
