Breastfeeding/pumping

Jessica
So I have a 5yo son but due to medical reasons he wasn't breastfed for longer than a week. I'm definitely planning on breastfeeding this baby and have everything I need for her except a breastpump and I'm due in just over 6 weeks. My question here is, if I'm planning on ebf do I need to pump? Wondering if it'll be a waste of money or if I actually need one.
