Thank you all for your replies

Arcadia- I tend to agree with your first comment there.
My DS had quite bad jaundice, he was an ECS at 40wks and fully BF, was VERY yellow, borderline going under lights, (was told he really should have, later)
his colouring took about 2-3 weeks to go away.

Nephew was born 3 weeks early (maybe) dates were a bit skewed the entire pregnancy...as far as I know, nothing was said by Doctors about his colouring, I was only told (in negative terms) what the nurses in SCN had told little brother and SIL about it...(As in they thought it was a bad thing that the mw's had done it)

hmm...
