So i guessing you were smoking before you found out you were pregnant?
Look its obviously not the best think to do, you know that.
But have you quit now? Thats the most important thing.
If not touch need to stop being selfish (harsh i know) that baby has no choice but to breath your air and deserves for it not to be filled with chemicals and toxins.
I was smoking up until the day before i found out i was pregnant with my first. But that morning i did the test i never would have lit a cigarette knowing i was carrying a tiny baby. I went on to have a beautiful baby boy.
