Biting while nursing!

Edit: She's definitely hungry. She keeps signing milk to me...and she sleeps through the night so she hasn't nursed yet. She bit me again twice this morning and I told her no each time and waited in between tries. Yesterday she cried because I was so stern with her when telling her no. Today she just stared. I tried making sure her latch was deep enough in case it was a bad latch and that wasn't it. She's 6 months and has her two bottom front teeth coming out already. I had to pump because my breasts were engorged from not nursing all night and her not nursing this morning. She's now not taking the bottle 😕 She has plenty of teething toys she used through out the day also...
