"Chuck E. Cheese scared me"

We went to Chuck E Cheese yesterday for Arden's playdate. Did I mention that we had 2playdates yesterday? 2 Playdates and a full day of work with no nap is the formula for meltdown to a 2 year old girl. Not a good idea, Mom. So she liked the games at CEC (I would say she likes things like the petting zoo better, she is not all that impressed with the games) but right before we were about to leave she saw Chuck E. on the stage and said " I want to go back to my shop, MA" When I asked her why she said that she said "Chuck E Cheese scared me right here (and pointed to her chest)" I laughed and took her back to the shop. He was on the stage. I can't imagine if he was walking around the restaurant.
So we also had playgroup at Andi's last night. Thank you Andi for letting us eat dinner with you. At the start Arden was just watching little mermaid being quiet and holding my arm. I could tell she was out of it. But everyone was walking around playing so i guess she decided to just do that too. Well, everything was "Mine" and she would push Addison or anyone else that tried to touch the toy that she had. Finally she found a tricycle--just like hers at home--that she wanted to ride. She did for a second but when I told her to get off and leave it alone she just went to pieces. She kept crying uncontrollable that " I want my bicycle." Even when I told her it is was Addison's--that made it worse. I spanked her for acting so ridiculous. Which I think scared some of the other kids. Sorry Amanda-Maddie's eyes were as big as saucers after I did that. She just kept on. The last straw was that she was playing with a toy and when Addi walked over she tried to yank it away and say "mine" and hit Addi on accident with the box. I was over it then. I just yanked her up and put her over my shoulder and said we were leaving. She cried but I didn't care. In the car on the way home I told her that we don't act that way. She didn't seem to care too much. I am not kidding-it was the worst she has ever acted in her whole life. I will take some blame for putting her through too long of a day because I had over-committed but still. By about 10min. in the car she was singing to herself so maybe she was just not in the mood to play? ???who knows.
