Hi Kim and Congratulations on your new son! I am now a first time grandmother of a 2yr. old. My daughter had to quit also during her pregnancy and as a mom, and it was hard but she did it. But here was 'nana ' going outside to smoke all the time.
You can do it. You are much younger than I and probably do not have the lung damage that i have at 58. I don't know if you are breast feeding or not, but if not, or talk to you Dr. try Chantix. It has really made a difference on my quitting this time.
Just do whatever it takes to quit,
Jan
