Screaming while eating

Sadie • 👨‍👩‍👧‍👧

Every night when I go to bottle feed my 7 week old she will suck once or twice on the bottle and then start screaming like she’s in pain and will continue to scream and not eat even though she’s definitely hungry and it’ll take about an hour to get her to eat at least an ounce during these times. But the rest of the day she eats just fine. She’s been doing this for about a month. Any ideas?
