I love how much the girls look out for each other. It seems that there is no one (not even Mommy) who is as in tune with their needs as they are.
Some mornings are more difficult than others. Addie wakes up grumpy and Ellie immediately jumps to "helping" mode where she helps Addie brush her hair and teeth just because Ellie knows that her little sister needs that extra support in the morning.
Some days are more difficult than others. Ellie comes home sad about some difficulties she has been having at school and Addie jumps to "cheerful" mode where she becomes all the more silly to get her big sister to smile. Worst case, she always has an extra hug or two for Ellie.
Sometimes words are not needed. Only actions.
