i agree ambah and shannon, some people say it can be harmful to quit cold turkey, but to continue smoking can be a hell of a lot more harmful.

i also agree with shannon, is easier if DP can support you and give up too, it is a lot easier. there is some percentage of higher instances of cot death when a baby is around cigarette smoke, maybe speak to DH about this, and see if he agrees it would be beneficial for you both to wuit, that way you can support each other, perfect!
