Breastfeeding

I really want to breast feed and would love any tips that helped you breastfeed your baby. Also My family is kinda discouraging me due to the comments they make such as “ you won’t b able to eat this because baby will get comics if u breast feed you can’t eat that or drink this blablabla”😩 it’s very overwhelming but I’m trying to keep a positive mind and really go forward with all this. So any tips or anything will help thanks ladies!
