Fed is best.

If you can breastfeed, that’s fantastic! But don’t be ashamed if you’re struggling to produce milk, it’s quite common and you shouldn’t avoid formula out of fear. It’s far worse for a baby to go hungry!

This is the answer. A fed baby is the goal. My wife exclusively pumps, and we supplement with formula when she gets sick or something comes up. The biggest reason I can give you to breastfeed instead of formula is that formula stinks. If you don’t clean a formula bottle up in time it reeks. A half empty bottle of breast milk can sit out a whole day and doesn’t smell much worse.
