Struggling

My LO is 2 weeks old today & we have been breastfeeding since day 1. She’s done awesome with the help of a nipple shield but we had to use a bottle twice one night because I had alcohol infused dessert & found out it wasn’t cooked out so I didn’t want her to get any in her system. She’s been doing okay since then with breastfeeding but since yesterday she is almost refusing to latch with or without a shield. I know we can work through it but it is really frustrating & also worries me about her getting enough to eat. She was bf for 20 minutes or so & now it’s BARELY 6-7😞 I’m just looking for help on how to get things back on track!
