smoke? cigarettes?

before you leave a comment, please no judgment or negativity here. i smoked all the way up until i found out i was pregnant! i haven’t smoked in almost a year. my daughter was born three weeks ago. she’ll be a month this thursday 💖💖 but ever since i had her i have CRAVED a cigarette. has this ever happened to any of you who smoked? i was considering just trying a small vape pen (outside of course) rather than just fully smoking cigarettes again. idk if it’s the stress or what especially since we’re in the process of moving. advice? or anyone else experience this?
