My partner smoked when I met him. I had no plans to have kids but knew that he did. The relationship moved pretty fast and we were engaged after a year. Married a year later and now expecting our first child 1.5 years after that. When we talked about kids he always said he wanted to give up prior ttc but he always struggled. He tried quite a few different stop smoking aids but was never successful. I didn't pressure him too much because unless you really want something for yourself you won't be successful. I am completely against smoking so once I was pregnant I took him to the doctors for a prescription to those stop smoking pills. He had a bad reaction to them so stopped taking them. He has been cold turkey since then and hopes he keeps it up. It's not just important to me for health reasons but also as a role model to our kids.
