What was harder, transition from 0 to 1 kids or 1 to 2?

Moms of at least two children, was it harder to go from 0 to 1 kids or 1 to 2? I struggled with PPD after my son was born and he was super colicky for the first 5 months. He is still very emotional and cries / freaks out any time I put him down. I love him but it’s been exhausting. My husband wants a second and I’m just wondering how I can go through this again. If you had a difficult time with baby 1 are the odds that baby 2 might be easier?
