Do you have siblings? Where do you fall amongst them? Do you think your personality was influenced by birth order?
I'm an eldest child. Since I am 7 & 10 years older than my brothers, I had to take care of them often. I cooked dinner, gave them baths, did more than my share of babysitting. I think it has impacted my level of responsibility growing up. Being so much older, I never experienced sibling rivalry and didn't feel competitive with my brothers at all. I felt more like an Aunt than a sister sometimes.
I was also old enough to experience what it was like to be an only child. A bit spoiled early on-- and also given a lot of attention prior to my brothers being born. This attention was a good thing, in terms of helping me learn to read, swim, cook, etc... fairly young, as I had that sort of one-on-one mentor-ship from all members of my family.
