She really proudly told me that she had been told you have smaller babies and put on less weight if you smoke ... So she started smoking while pregnant.
Another one I met at a dh work party this lady was smoking non stop all night she had 3 kids I could see and she kept handing her youngest to the older kid when she had a smoke (obviously didn't want it around smoke!) ... But people kept talking about her 4 kids and I'm counting them all night but could only see 3 ... Eventually I asked dh apparently she was preg.
I don't mean to demonise mums who smoke I don't these are the norm ... I have been told they are better to cut down as much as possible rather than entirely.
I've never smoked so wouldn't begin to imagine what the addiction must be like.
