Marijuana & breastfeeding

Before becoming pregnant with my baby girl I smoked daily. I had been smoking for years and quit the day my test had two lines 💘 I've not smoked at all in 20 weeks! I'm not looking for judgement, even though I know most of the time that's all anyone gets from marijuana posts, but I want to know how marijuana and breastfeeding works/if it does. I didn't know if it was like alcohol and breastfeeding or what. So if you guys have any FACTS please let me know :) I don't plan on doing it, but if it is safe I would like to be able to smoke every now and again once she is here!Â
