I know smoking is bad and it can get in your milk and you got to wait a certain amount of time before feeding again and it can mess with your supply. But my question is how do you really know if its the nicotine and not stress?. Im excessively breastfeeding and i pump occasionally. I feel like my supply is decreasing, it may not be but the way my Lo suddenly acts when being fed tells me other whys. I started not to pump at night a and wait till he wakes up to relieve my engorgement breast but i know that can decrease my supply anymore. So if there is any moms who smoke and breastfeed i would really love some feedback or advice. Thank you!
