I smoked from the age of 14 but stopped for all my pregnancies including this one. You ask for honesty and i will give it, from my opinion. Its an addiction, i was certainly addicted, 20+ a day. But if you want your baby to have the best start possible you will do your upmost to quit. Even if you cant, but you try your best, cut down, go to lighter smokes, anything like that all counts. There is always someone whom smoked, drank, took drugs etc in their pregnancy and had normal healthy labours and children, it DOESNT mean that will always be the case with anyone else whom does the same. Its a case of weighing it up, deciding whats the most important.
As i say, if you try all you can then thats enough, even if you dont manage to stop fully. I know some midwives advise cutting down first before quitting as stopping totally can be a shock to your body. Dont beat yourself up about it, but do try your best. xxx
