Very interesting. Definitely could see my own traits listed there.
With my own kids though, there 4 years between my eldest and my middle and I find that he has some traits of the eldest born and some of the middle. My 3rd little guy is definitely the last child born - the article could have been about him :)
i enjoyed reading this today it was interesting and so true of me and my husband - we are both first born. for me interesting to see if my kids fitted into the research.
