IdDTD (is that right?!) are 5, has anyone else read anything about certain character traits on 1st & 2nd born twins?

I know I read something about this sometime after the birth, but as the first 2 years were lost in the morass of sleep deprived insanity rather a blur, a don't know where it was. The topic was about some generalised character traits and behaviours that have been found in studies of 1st and 2nd born twins. Does this ring a bell with anyone? Am asking as DTD1 is more anxious and DTD2 is more easy-going and I have this feeling I've read something pertaining to it...
sigh
twin brain strikes again
not looking for ultimate answers to why they are how and who they are, it just popped into my head tonight and would like to know if I've made it up! (I was thinking, having someone sitting on your head for 9 months would make anyone anxious, and having a reasonably comfortable sibling as your pillow for 9 months would also make you feel pretty good about life )

I hope you get the answers/explantions you're after. DS suffered with fluid levels and it definetly effected his size. I agree with that the size should have been enough. Good luck with it all xx

Hoping it is just an unclear scan but there was a slight concern about a bright mass showing up. Should have bern reffered days after 20 weeks scan but got messed up somehow and my refferal was for 24 weeks! However the lovely receptionist lady has booked me in earlier! Urgh.

I know it's not a great comfort but at least you only have days to wait not wks. Waiting is the worst bit, especially if like me you spend many hrs awake over thinking things. Good luck xx
