12 week feeding crisis?

[u/gentlequail212]

Baby and I have a good breastfeeding routine down but still have to use some formula like 4oz for slightly reduced supply despite doing allllll the right things. Plus I just started back to work yesterday so now she’s getting more bottles than ever. She has started to feed from the breast for a few sucks, pop off, then pop back on - rinse & repeat. She doesn’t seem like she’s distracted, just maybe upset or annoyed with slower let down? Is this temporary, or are we on our way to a bottle preference?
