Help?

Hey, so I was wondering if anyone could help me calm down about breastfeeding after baby is born lol, I’m only 6 weeks pregnant right now, but I know I defiantly want to breastfeed this baby, I’m really anxious about how it will go, especially with an almost 2 year old. I’m especially nervous about breastfeeding in public. Is there a certain breast feeding cover that everyone likes? Or a baby wrap that helps you breastfeed while doing other things as well? Any medication I can’t take while breastfeeding? And how to make it more comfortable? And what pump is good to use? And does anyone breastfeed during the day and afternoon, but then pump and bottle feed at night so that the dad can feed the baby in the middle of the night? I’m really anxious about it lol I know it’s still a long ways away until I will actually have to breastfeed, but I like to plan ahead lol any help would be appreciated!
