Bottles & breastfeeding?

Autumn • mama Baby #2 on the way🤍 Instagram: autumnleiigh23

I plan on breastfeeding & I will be a stay at home mom. I already have tons of bottles also bought an electric pump. I know it depends on how much milk I produce but will I really need to pump if I always have boob on tap lol? How many bottles do you think I’ll really need on a daily basis if she’s just drinking out of the boob?? First time mom lol thanks in advance
