Good luck Carrie...
I've known a couple people with serious lung and heart conditions cause their mothers smoked while they were in the womb. Could never play sports or engage in too much physical activity, in addition they never could not smoke anything themselves either as the doctor said it was not a good idea. They have suffered their entire lives cause mom needed to smoke during pregnancy. Such a shame.
I've never been a cigarette addict or a mom, but congrats on the pregnancy.
