angelico - scary, but as I understand it, fresh red is the big worry and brown is the less-big worry (though still pretty damn worrying!) (And
Jumping in on the vitamin d thing - they had a thing about this on the radio the other day, the science man (that's the technical term, that is) said that vit d is made in the skin under exposure to sunlight, but basically no-one in the UK makes any in their skin between September and May so vit d tablets for us is probably a really good idea. The deficiency leads to rickets (rickets! So Dickensian!)
I don't know if anyone here is Asian or Black or has otherwise high melanin content in their skin (I wear makeup shade 001, personally - I have skin the shade of a fish's underbelly) but the more melanin, the harder it is for your skin to turn sunlight into vitamin d, so the more good an idea it is to take the supplement pills.
Oh and briefly, a note on booze - may I direct your collective attention to this. It's a review of medical literature - they've read over lots and lots and lots of research and tried to pick out patterns. Here is your key take home:
"Studies involving a total of about 150 000 pregnancies sought a link between low-level alcohol consumption and abnormal pregnancy outcomes. Very few showed a statistically significant link, and the results are undermined by the failure to take other risk factors into account... Studies in a total of 57 000 pregnancies showed no effect of minimal alcohol consumption on the risk of malformations."

Pubmed itself is a database of online medical journals - the Good Stuff, if you will. A lot of medical research isn't free to read, but this stuff is.
(Another tip-top place for accurate, usable health info - squidkid will, I think, tell you the same - is cochrane.org. They do the same thing, they scan all the research they can find and try to come to scientifically valid conclusions about treatment. It's not always an easy read, but it's always bang up to date - and as accurate as science can be.)
(Actually when I clicked through to get the URL this was the feature article: www.cochrane.org/features/pain-management-women-labour-overview-systematic-reviews and that's a topic that I think we're all interested in!)
