Breastfeeding Changes at 9 weeks

LO is 9 weeks old and has been nursing w a shield. Was going fine then all of a sudden she started latching great without it!! She was fine without it for a few days then Monday and today she has refused the breast with and without the shield. she took a bottle great and I tried to pump for each missed feed but it's hard to do when I'm home alone during the day.

I guess I'm just frustrated bc I feel like I'm going to lose my supply this way. If were going to have to switch to formula that's okay... Just disappointing after we've gotten through this far and she JUST stopped using the shield. Either way, I'd like to pick a side... Going back and forth is challenging.

Did anyone else experience changes/difficulties w refusal around 9/10 weeks old?
