No advice, just wishing you both well as you try to kick the habit. And I am impressed that you both want to. I see so many hugely pregnant women puffing away and it drives me mad.
I know you both can do this.
Join the club. I'm praying for terrible morning sickness to make me quit. I wean slowly, but I immediately cut down to 3-5 a day. It is difficult, and I drink water instead. I quit every time I'm pregnant, and as soon as I'm no longer pg, I start again...This is my 4th pregnancy. I'm only 4 weeks. I haven't smoked today, but I will. It is so hard, but you have to start with cutting back. I don't know your smoking habits, or I would give you more ideas.
