2 older brothers and one older sister. I am the baby. None of them are addicts or married addicts. None of them are codies either.
Mich, yes I have heard that if there are many years between the younger one does have more of the "1st child" traits. I have a 20 year old and an 18 year old, an 8 year old and 5 year old. The 8 year old does have a lot of "first-child" traits... responsible, always wanting to do the right thing, etc.
