zippi: my grandmother was actively encouraged to drink Guinness daily while pregnant as it was thought to help the baby. My MIL recalls several times she got absolutely plastered then thought she might refuse the next glass of wine because the baby's movements were a bit less than normal.
The advice to only drink 1-2 units a week is fairly recent and WAS based on proper scientific evidence. The move to no units is not based on scientific evidence.
There is no such thing as no risk.
Next we'll be saying pregnant women shouldn't use computers or a mobile phone "just in case". For gods sake don't let them cross the road, they can't be trusted to judge speed correctly with all those hormones. I know let's just herd all pregnant women into special centres so we can keep an eye on them and stop them doing anything silly (oh wait... that last one might actually cost us money, better not do that).
There was other advice I ignored too. Ignored the runny egg one as I craved soft boiled eggs and soldiers. I did the research, made sure I got free range, lions marked eggs (that's hens vaccinated against salmonella) and decided the risk was small enough to not be significant. Other pregnant women won't want to take that risk and that's fine.
There's an increasing movement in parenting these days that if you're not in full martyr mode, not sacrificing everything, actually happy then somehow you're a crap parent and neglecting your children. For gods sake, you're not supposed to ENJOY parenthood! It's a big sacrifice for the human race, donchaknow.
There was a time when having children was just a state of being, something that you did, not a whole "life choice" that you needed to validate at every turn by self-flagellation.
