Exclusively pumping?

Has anyone here exclusively pumped and had good luck with it? Im considering doing it, but with 2 toddlers, it seems easier just to nurse. My breastfeeding journey with both my other kids was rough to start due to having flat nipples causing latching issues which led to a lot of pain on my part and having to use nipple shields which effected my supply over time. When my first baby was born early I had to pump at first for a while and responded really well to it, probably like twice as good as breastfeeding, which is making me consider exclusively pumping. Is it a thing to nurse AND pump?? What would that look like in terms of a schedule? I feel like i should have this stuff figured out by now being baby #3 but I'm having a crisis 😅
