As I am reading this I am enjoying a small glass of red...
I didn't drink during first tri but since then I am allowing myself a glass on the weekend if I fancy it, which I don't always - last couple of weekends I haven't.
I only drink very nice, pricy wine at the mo. I figure since it is occasional I may as well go for something good.
No expense spared for my baby I have quite expensive taste anyway, and not really into spirits, aside from gin, but I haven't fancied it, and like to kid myself that there are health benefits associated with red wine (who knows whether there are or not? Just one more thing the 'authorities' continually change their minds about).
My grandmother, mother, MIL and GMILs drank a healthy amount when pregnant and the NHS guidelines change weekly; I personally don't believe there is any harm in the occasional glass. I'm not a scientist and not everyone will agree with this but it isn't their body or their baby...
