3 month old is refusing to nurse unless drowsy or asleep


My 3 month old has started only eating if she’s drowsy or asleep. If she’s awake she’ll latch and suck for a second and then pull off. She’ll do this a few times before refusing to eat at all. This started about 5 days ago and I have no idea why.

Has this happened to anyone else?

Does anyone have any tips?

I don’t know what to do.

Thank you!
