Certain foods to avoid when breastfeeding??

Kellie • First time mommy to a babygirl named Lillie ☺️💕

So I’m currently 31 weeks pregnant and plan on breastfeeding once my lil one is here. No one has ever told me that I should avoid certain foods while doing this since it won’t be good for my baby. I’ve never even heard of this as a FTM. What should I avoid once babygirl is here? 🤷🏼‍♀️🤷🏼‍♀️
