I don't have a problem with the odd drink during pregnancy. That said I totally lost my taste for alcohol and coffee when I was pregnant. I had one glass of wine on my birthday and have only had a couple of glasses since ds was born. The thought of waking at six thirty puts me off.
What really surprised me when I was pregnant and going to antenatal classes and hospital visits was the number of pregnant women who still smoke. Now I have never smoked so I probably don't understand how hard it is to give up but I found it very strange.
