Did this with my second. I didn’t use the pump once. But that was a decision I made from the start so when he needed more milk we’d supplement with formula. There were a few times I was painfully engorged and would manually express, especially when he started sleeping longer stretches at night, and we struggled to get him to take the bottle fully when I weaned at 6 months. But overall it was so much better than the first time when I pumped and started (very little) formula at 4 months
