I prefer to think that Rachel has simply been trying to assert herself recently.
She is a very loving, gentle and caring 6th year old girl and a wonderful big sister to Natalie.
But recently she has been kind of cranky: "I do not want take a bath tonight (her hair needs to be washed, her tush is red and her hands are nails need to see the water..), I do not want to brush my hair, I don't want to wear that dress (eventough that's what she had agreed on the night before), I do not like this or I hate that" (we do not accept that word in the house). Some stuff I can let go, such as picking up other clothes or not wanting to brush her hair (I would rather like her to look great when she goes to school but ...). If I force her, she starts crying and that can last for 30 minutes. Yossi tends to think that I should not sweat the little things and I do agree, the battle sometimes is not worth it. But when it comes to being clean, it is a no no in my book.
Another example: On valentine's night, she had a big party at school and I guess too much sugar, she was tired and cranky. She had just told me that she did not care for a girl in her class and ripped off her valentine card (will have to ask her more about Katie). When Yossi bought flowers and ballons for everyone, she decided that she did not like hers and put it in the trash. We were not pleased and I talked to her and asked her to apologize, which took awhile and a lot of crying for her to do.
I do not want of course to bend her strong will but it worries us a little bit I have to say.
