Nursing after previously Exclusively Pumping

If you previously exclusively pumped for one child and successfully nursed for another, what did you do differently? I had to EP for my ten month old, and I gave up around 10-12 weeks because of allergies and horrible PPD/PPA. I’m pregnant again, and I would seriously rather do formula over touching a pump ever again, but if I can make nursing work, I’d love to. Advice needed please!
