Oh great, so we've got to worry about prenatal developmental milestones now as well, have we?
Well, CK1, we're not far into our first trimester so you have exposed your baby to what - 8 units? - at the most? This is a lot less than I poured on top of my DS before I knew I was pregnant the last time around . No sign of ADHD yet!
IMHO, that article is badly written, to the point of being misleading. The US studies quoted are presumably those that investigate the nature of fetal alcohol syndrome, which is normally the result of abnormally heavy drinking, well beyond the recommended limits in the UK. Further, I find it suspicious that the Professor leading the study doesn't make any comments about why the 61% of babies born to the mothers who drink don't seem to display this primitive startle reflex but have the developmentally correct startle reflex. The thesis is that babies exposed to any alcohol develop differently/more slowly, but repeated studies have been unable to demonstrate any link to damaged postnatal development, health or IQ of babies exposed to small quantities of alcohol in the womb.
Having said that, if other studies support these findings, it seems perfectly sensible to put some wording on alcohol along the lines of 'drinking during pregnancy will affect the prenatal development of your baby' and let us all make our own minds up about the relative importance of achieving prenatal developmental milestones vs relaxing with a glass of wine, since it all boils down to your attitude to risk and the balance of your life against the babies.
My own experience is that with my first pregnancy, I tried to follow the general medical advice not to drink for the first three months, but in honesty, because I didn't feel very pregnant (only slightly nauseous and a bit tired) and because I was rather ambilivant about the whole idea of having a baby, I did have one or two drinks during that time. I then drank around 4 units a week throughout the rest of my pregnancy. My feelings have changed now I'm a mum and I am more sensitive to risk, so it seems easier to give up the booze entirely at the moment. I'm certain I will be happy to get back to the odd glass of wine as a treat after christmas though.
