There are of course the physical similarities: hair color, eye color, long legs and shorter torso, eye shape, etc. My daughter also has my height and my feet. Growing up I was frequently the tallest girl in my class, if not the tallest kid at all. So far she has gone anywhere from the 85th to 110th percentile in height. And, along with the height comes shoe size.
Today I wear a 10. It was an 8 1/2 in college, but for some reason y feet just keep growing. In kindergarten, K wears a 1 1/2. When we last went into Stride Rite (she was three) they said they didn't offer anything else in her size. Since then, I've been ordering her shoes online. Its the only way to get something in her size that doesn't - A: have laces (she can't tie them yet) or B: look way too old (high heels!).
K also reminds me of myself when I was young. She is strong willed, and wants to do things her way. Even small things like writing her name at school. She wants to print her name in all caps. The teacher (and I) would like her to use cursive. There is no changing her mind though. She'd rather get in trouble for not doing work than to do it some other way.
I could go on and on. Instead I will just quickly mention one of my traits I am VERY glad she didn't get - athletic ability. I couldn't play sports to save my life when I was a kid. K on the other hand has done soccer, swimming, ballet and others. Thank goodness.
