@Karina I’ve been trying for about 5 minutes until moving onto the bottle. You’d suggest trying longer for her to latch?
Yes! I know it can be confusing because sometimes she’s simply tired. I started walking/bouncing her as she’s feeding and it helped me get her to stay on without getting upset. I know that can be a lot and I’m not sure if it’ll work but worth a try
She might be upset the your milk isn’t coming out as fast as it would with a bottle. My baby gets upset with this and I basically let her cry as she tries to drink my breast milk and within 10 mins she gets it. Hope that’s helpful!
