Breastfeeding question...

Okay so my little girl is now 24 hours old. She latched onto the right boob perfectly and will feed for 15-30 minutes. But she will NOT latch onto my left boob. Like no matter what position. This hospitals Lactation consultant told me to just keep trying different ways of holding her but it’s like she just hates that boob. As soon as I stop trying with that side and stick her on the right, she latches and eats until she’s done. Is there anything I can do to get her to latch to the left? The LC told me to feed her on the right and pump on the left if she won’t latch.
