This is a really interesting thread and a brave one to start, but good on you for doing so. It's really interesting to read everyone's opinions.
Personally, I hate to see pregnant women smoking. I try not to judge, and would certainly never preach at anyone, but I can't look when someone's doing it. My friend has smoked throughout her pregnancy and has had a really rough time - water infections, terrible sickness (even still now in the 3rd tri) and recurrent colds/chest infections. Not saying thats all caused through smoking, but I don't understand how she can't face much more than a sip of tea sometimes, yet she can always face a fag.
I quit smoking years ago so I know how difficult it is, but have been a social smoker on and off for about three years. Had my last one the day before I found out I was pregnant and my initial reaction to the positive pregnancy test was "oh my, I need a cig" but resisted! Now, having gone this long without one, I'll never touch another one. My hubby always says "never say never" but nooooo way, I really mean this one.
