You don’t have to pump if you breastfeed. I got so little when I did it compared to how much she fed it felt like a chore. I wouldn’t buy now imo just wait and see
All the advice I’ve had is to not buy a pump until after birth and knowing you need one. You’re not meant to pump for the first few weeks anyway due to establishing supply
You don’t need one but often people pump and feed. It depends what your preference is!
