Ds7 has always been emotional and sensitive. He got upset if he made a mistake, but got over it quickly with some cuddles and something to distract him. Dd4 is proving to be a bit more challenging. We were working on some math problems today, and she was doing really well. But on one particular problem, she got the wrong answer several times in a row. Not a big deal - this happens to everyone. But she started screaming at me and crying hysterically. I tried to calm her down while making sure she understood that screaming at me was not acceptable. It took a few minutes, but she finally looked up through her tears and said, "Mommy, I was trying to be perfect!" I thought I was going to start crying as well. She's talked a lot about trying to be perfect lately, but only as it relates to behavior and attitude. I encouraged her to try, while mentioning that everyone makes mistakes sometimes. I didn't realize she was trying to be perfect in every aspect of her life. It has been two hours now, and while she has calmed down a bit, she is still crying periodically and nothing I've done has helped. Any suggestions?
