It's a mind altering substance regardless, I just wouldn't. If you can read medical jargon there's lots of studies out there a Google search away. If you have to ask, it's probably not a great idea
Personally I did use a little bit when breastfeeding I waited 2 months to really get my milk supply in and then I would start to puff again. I don’t take edibles again untill after my kids started eating solid more often.
Not enough research but I’ve read one study only 0.007% is transferred to breast milk and that’s only if you a chronic smoker
There’s not enough research on how it affects babies, I suggest just waiting until you’re done breast feeding.
